A bruise often moves toward the nail tip as the nail grows. However, a dark band that widens, spreads onto surrounding skin or appears without an obvious injury needs medical assessment. People with diabetes should not attempt to drain blood beneath the nail at home.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Discovering a black patch beneath your toenail can be worrying, especially when you have diabetes. Sometimes the cause is a minor injury from tight shoes or repeated pressure. In other cases, the discoloration may indicate an infection or another condition that requires investigation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diabetes can make nail injuries more serious because neuropathy reduces pain sensation, while poor circulation and high blood glucose may interfere with healing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the possible causes of <strong>black toenail diabetes<\/strong> symptoms helps you recognise when to seek medical attention.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Turns a Toenail Black in Diabetes?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Several conditions can cause dark discoloration beneath or within a toenail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Subungual Haematoma (Blood Under the Nail)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A subungual haematoma occurs when blood collects beneath the nail following an injury.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common causes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Accidentally hitting the toe<\/li>\n\n\n\n<li>Wearing tight footwear<\/li>\n\n\n\n<li>Repeated pressure during walking<\/li>\n\n\n\n<li>Dropping something onto the foot<\/li>\n\n\n\n<li>Toenails pressing against the front of shoes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The affected nail may appear red, purple, dark brown or black.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some people experience throbbing pain. However, patients with diabetic neuropathy may feel little or no discomfort.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A small bruise may gradually move outward as the nail grows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read more about <a href=\"https:\/\/www.suratdiabeticfootcare.in\/diabetic-foot-conditions\/nail-conditions\/nail-hematoma\">Nail Haematoma<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Fungal Toenail Infection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fungal infections can change the colour, thickness and texture of toenails.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible symptoms include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Yellow, brown or dark discoloration<\/li>\n\n\n\n<li>Thickened nails<\/li>\n\n\n\n<li>Brittle or crumbly nail edges<\/li>\n\n\n\n<li>Debris beneath the nail<\/li>\n\n\n\n<li>Nail separation from the nail bed<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Fungal infections can coexist with trauma, so appearance alone may not establish the cause.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A clinician may collect nail clippings or debris for fungal testing before recommending treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See <a href=\"https:\/\/www.suratdiabeticfootcare.in\/diabetic-foot-conditions\/nail-conditions\/fungal-nails\/\">Fungal Nails<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Subungual Melanoma<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Subungual melanoma is an uncommon but serious form of skin cancer that can develop in the nail unit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may appear as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A new dark vertical band<\/li>\n\n\n\n<li>An irregular brown or black patch<\/li>\n\n\n\n<li>Pigmentation spreading onto surrounding skin<\/li>\n\n\n\n<li>A progressively widening dark band<\/li>\n\n\n\n<li>Nail splitting, distortion or bleeding<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Not every dark band indicates melanoma. Benign pigmentation, trauma and other nail conditions can look similar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, suspicious pigmentation requires prompt assessment by a dermatologist or an appropriate specialist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A dark nail that does not grow out normally should not automatically be assumed to be a bruise.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Tell a Bruise From Fungus or Melanoma?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following comparison highlights typical differences.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Feature<\/th><th>Bruise (Haematoma)<\/th><th>Fungal Infection<\/th><th>Nail Melanoma<\/th><\/tr><tr><td>Injury history<\/td><td>Often present<\/td><td>Usually absent<\/td><td>May be absent<\/td><\/tr><tr><td>Colour<\/td><td>Red, purple, brown or black<\/td><td>Yellow, brown, white or occasionally dark<\/td><td>Brown or black, sometimes irregular<\/td><\/tr><tr><td>Moves with nail growth<\/td><td>Usually<\/td><td>Variable<\/td><td>Pigmented bands often persist from the nail base<\/td><\/tr><tr><td>Spreads onto surrounding skin<\/td><td>Unusual<\/td><td>Unusual<\/td><td>Possible warning sign<\/td><\/tr><tr><td>Pain<\/td><td>May be painful or painless<\/td><td>Often painless<\/td><td>May be painless initially<\/td><\/tr><tr><td>Nail thickness<\/td><td>Usually unchanged initially<\/td><td>Often thickened<\/td><td>May become distorted<\/td><\/tr><tr><td>Main assessment<\/td><td>Examination and monitoring<\/td><td>Nail testing when indicated<\/td><td>Specialist examination and possible biopsy<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These findings are clues rather than a reliable home diagnostic test.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A clinician may use dermoscopy, photographs and follow-up measurements to distinguish the conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For additional information, visit <a href=\"https:\/\/www.suratdiabeticfootcare.in\/diabetic-foot-conditions\/nail-conditions\/discoloured-nails\/\">Discoloured Nails<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Diabetic Nail Care in Valsad: When Should You Seek Medical Attention?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">People seeking <strong>diabetic nail care in valsad<\/strong> should arrange medical assessment for unexplained black nail discoloration, particularly when neuropathy, poor circulation or previous foot ulcers are present.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seek urgent medical care if you notice:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Redness or swelling spreading around the toe<\/li>\n\n\n\n<li>Pus, foul-smelling discharge or an open wound<\/li>\n\n\n\n<li>A toe becoming cold, pale or newly black<\/li>\n\n\n\n<li>Fever or rapidly worsening infection<\/li>\n\n\n\n<li>Severe pain following an injury<\/li>\n\n\n\n<li>Bleeding that continues or repeatedly returns<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A new dark band, pigmentation extending onto nearby skin or a changing nail lesion also requires prompt specialist evaluation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not wait for the toenail to fall off before seeking help.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the ABCDEF Checklist for Nail Melanoma?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The ABCDEF rule is a clinical awareness tool used to identify features that may raise concern about nail melanoma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A :  Age and Ancestry<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nail melanoma is more often diagnosed in middle-aged or older adults, although it can occur at other ages. Certain ancestry groups have higher proportions of nail melanoma among their melanomas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>B : Band<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A brown or black band, especially one that is broad, irregular or widening, deserves assessment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>C : Change<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Changes in colour, width, shape or nail structure may be concerning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>D : Digit<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nail melanoma can affect any digit, but the thumb, big toe and index finger are commonly described sites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>E : Extension<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pigment extending from the nail onto the cuticle or surrounding skin can be an important warning sign.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>F : Family or Personal History<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A personal or family history of melanoma or atypical pigmented lesions may increase concern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ABCDEF rule does not diagnose melanoma. Some melanomas lack these features, and benign conditions can share them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A suspicious lesion should be assessed without waiting for every warning sign to appear.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Should Blood Under the Toenail Be Drained?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A painful subungual haematoma sometimes requires drainage to relieve pressure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clinicians may perform a procedure called nail trephination, creating a small opening in the nail plate to release trapped blood.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, drainage is not necessary for every bruise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The decision depends on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The time since injury<\/li>\n\n\n\n<li>The amount of blood beneath the nail<\/li>\n\n\n\n<li>Pain and pressure<\/li>\n\n\n\n<li>Nail integrity<\/li>\n\n\n\n<li>Possible fracture<\/li>\n\n\n\n<li>Circulation and infection risk<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">People with diabetes should never attempt drainage using heated objects, needles, blades or other home methods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These methods can cause burns, wounds or infections, particularly when foot sensation is reduced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A trained clinician should assess the toe and perform any required drainage under appropriate clinical conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Are Toenail Injuries Riskier With Diabetic Neuropathy?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Diabetic peripheral neuropathy damages nerves responsible for sensation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A patient may not notice pressure, friction or injury until visible changes develop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, tight shoes may repeatedly press against the big toenail during walking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Over time, this pressure can cause bleeding beneath the nail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the injury may not hurt, the patient might continue wearing the same shoes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Repeated pressure can damage surrounding skin and increase the risk of ulceration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diabetes-related circulation problems can further complicate healing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, even a seemingly minor toenail injury deserves careful attention when neuropathy is present.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Shoes Cause Repeated Toenail Bruising?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Poorly fitted footwear is a common source of repeated nail trauma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Risk factors include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Shoes that are too short<\/li>\n\n\n\n<li>Narrow toe boxes<\/li>\n\n\n\n<li>Shoes that allow the foot to slide forward<\/li>\n\n\n\n<li>Tight or poorly positioned seams<\/li>\n\n\n\n<li>Excessive pressure over thick toenails<\/li>\n\n\n\n<li>Footwear that does not accommodate toe deformities<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How to Reduce Nail Pressure<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Choose shoes with sufficient toe space and a secure fit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check the inside of footwear for rough seams, stones or other objects before wearing it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Avoid walking barefoot, especially if sensation is reduced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A footwear assessment can identify pressure points and help determine whether protective or customised footwear is needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read more about <a href=\"https:\/\/www.suratdiabeticfootcare.in\/footwear-services\/preventive-footwear\/shoe-fitting\">Diabetic Shoe Fitting<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Happens During a Black Toenail Examination?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A clinician usually begins by examining the affected nail and surrounding skin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The assessment may include:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Reviewing recent injuries and footwear.<\/li>\n\n\n\n<li>Checking the colour, shape and location of the dark area.<\/li>\n\n\n\n<li>Examining the nail plate and nail folds.<\/li>\n\n\n\n<li>Testing foot sensation and circulation when indicated.<\/li>\n\n\n\n<li>Taking a photograph and measuring the pigmentation.<\/li>\n\n\n\n<li>Performing dermoscopy or arranging specialist assessment.<\/li>\n\n\n\n<li>Considering fungal testing, imaging or biopsy where appropriate.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">For a lesion that confidently appears to be a bruise, a clinician may document its position and arrange review after approximately four to six weeks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During follow-up, the clinician checks whether the discoloration is moving toward the nail tip.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, <strong>a suspicious pigmented lesion should be referred promptly rather than waiting four to six weeks<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Is a Nail Biopsy Necessary?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A biopsy involves collecting a small tissue sample for examination under a microscope.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may be recommended when a clinician suspects melanoma or another condition that cannot be diagnosed confidently through examination.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Possible reasons include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A progressively widening pigmented band<\/li>\n\n\n\n<li>Irregular pigmentation originating near the nail matrix<\/li>\n\n\n\n<li>Pigment spreading onto surrounding skin<\/li>\n\n\n\n<li>Unexplained nail destruction<\/li>\n\n\n\n<li>A persistent suspicious lesion without a convincing injury history<\/li>\n\n\n\n<li>Recurrent bleeding or a growing nail-unit lesion<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A nail biopsy should be planned by a clinician experienced in nail-unit assessment because the location of the sample matters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not every black toenail requires a biopsy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, persistent or changing pigmentation should not be dismissed simply because the patient has diabetes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does a Black Toenail Take to Grow Out?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Toenails grow slowly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A complete toenail replacement commonly takes around 12\u201318 months, sometimes longer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bruise beneath the nail may become less noticeable as healthy nail grows from the base.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The nail may occasionally loosen or fall off after significant trauma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the appearance of a new nail depends on whether the nail matrix was damaged.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Patients should avoid pulling off a loose nail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the nail separates, a clinician can assess whether protective care or treatment is required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Can You Prevent Black Toenails With Diabetes?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Daily foot care helps identify injuries before they become serious.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Recommended precautions include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Inspect your feet and toenails every day.<\/li>\n\n\n\n<li>Use a mirror or ask for assistance when necessary.<\/li>\n\n\n\n<li>Wear properly fitted protective footwear.<\/li>\n\n\n\n<li>Avoid cutting nails too short.<\/li>\n\n\n\n<li>Trim nails straight across without digging into the corners.<\/li>\n\n\n\n<li>Keep feet clean and dry.<\/li>\n\n\n\n<li>Avoid attempting to remove thick or damaged nails yourself.<\/li>\n\n\n\n<li>Arrange professional foot care when sensation or circulation is reduced.<\/li>\n\n\n\n<li>Follow your diabetes management plan.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you notice new discoloration, document when it appeared and arrange an assessment rather than trying home remedies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Should You Consult a Diabetic Foot Specialist?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A diabetic foot specialist can evaluate whether the dark nail is associated with trauma, pressure, infection or underlying circulation problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For unexplained pigmentation, a dermatologist may also be needed to assess for melanoma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Early evaluation can prevent avoidable complications and identify serious conditions sooner.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Ashutosh A Shah, MBBS, MS, MCh, DNB, is a Plastic and Reconstructive Surgeon who has been practising since 2004. Patients with complex foot wounds or nail-associated tissue problems may require multidisciplinary assessment involving diabetic foot clinicians, dermatologists and other specialists. Nail melanoma concerns require appropriate dermatological evaluation and biopsy planning.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1793005274995\"><strong class=\"schema-faq-question\">1. Is a black toenail dangerous for diabetics?<\/strong> <p class=\"schema-faq-answer\">It can be. A black toenail may result from a bruise, infection or rarely melanoma. People with diabetes should have unexplained discoloration examined, especially if neuropathy or poor circulation is present.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005286415\"><strong class=\"schema-faq-question\">2. Will a black toenail fall off?<\/strong> <p class=\"schema-faq-answer\">Sometimes. A nail damaged by significant bleeding or trauma may loosen and detach. However, many bruised nails remain attached while the discoloration grows out.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005314494\"><strong class=\"schema-faq-question\">3. Can I drain blood under my toenail at home?<\/strong> <p class=\"schema-faq-answer\">No. Home drainage can cause injury or infection. A clinician should decide whether drainage is necessary and perform it safely.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005321535\"><strong class=\"schema-faq-question\">4. Can a black toenail be cancer?<\/strong> <p class=\"schema-faq-answer\">Yes, although uncommon. Nail melanoma may appear as a dark band or patch. Changing pigmentation or pigment spreading onto surrounding skin requires prompt specialist assessment.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005333895\"><strong class=\"schema-faq-question\">5. Why is my toenail black without any injury?<\/strong> <p class=\"schema-faq-answer\">Possible causes include unnoticed pressure from footwear, fungal infection, benign pigmentation or melanoma. Neuropathy can make minor injuries difficult to detect.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005346311\"><strong class=\"schema-faq-question\">6. How long does a toenail take to grow back?<\/strong> <p class=\"schema-faq-answer\">A complete toenail may take approximately 12\u201318 months to regrow. Recovery depends on the extent of damage to the nail and its growth centre.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793005360966\"><strong class=\"schema-faq-question\">7. Where can I get diabetic nail care in valsad?<\/strong> <p class=\"schema-faq-answer\">Patients seeking diabetic nail care in valsad should consult a qualified diabetic foot clinician or dermatologist for unexplained nail discoloration, injury, infection or suspicious pigmentation.<\/p> <\/div> <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>black toenail diabetes<\/strong> concern should never be ignored simply because it is painless.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many black toenails result from minor trauma or repeated footwear pressure. Others may involve fungal infection or, rarely, melanoma.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bruise typically moves outward as the nail grows, while suspicious pigmentation may persist, widen or spread.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Professional examination, appropriate monitoring and timely biopsy when indicated help distinguish harmless injuries from serious conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If you have diabetes and notice a new black toenail, arrange a clinical assessment rather than attempting home treatment.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A black toenail with diabetes may be caused by bleeding beneath the nail, a fungal infection or, rarely, nail melanoma.
