Quick answer: Toenail Trauma Black Nail Michigan is a common nail condition with multiple causes including trauma, fungal infection, biomechanical pressure, and underlying medical conditions. Treatment depends on the cause: trauma resolves as the nail grows out (6-12 months), fungus needs antifungal therapy, and biomechanical issues need shoe and orthotic correction. Call (810) 206-1402.

▶ Watch
A black toenail — medically a subungual hematoma — develops when blood accumulates under the toenail following trauma or repetitive pressure. It is one of the most common foot conditions seen in runners, hikers, and anyone who has stubbed a toe or dropped an object on the foot. While most subungual hematomas are painful but benign, certain presentations warrant professional evaluation to rule out underlying fracture, nail bed laceration, or — rarely — subungual melanoma (a dark pigmented lesion under the nail that requires biopsy). At Balance Foot & Ankle in Southeast Michigan, Dr. Tom Biernacki evaluates nail trauma promptly and provides appropriate treatment ranging from simple trephination (pressure relief) to nail bed repair.
Causes
Acute subungual hematoma typically results from blunt trauma — a dropped object, a stubbed toe, or a crush injury. The nail bed bleeds beneath the nail plate, creating a painful, pressurized dark red to black discoloration. Runner’s toe (also called “jogger’s toe” or “tennis toe”) is a chronic form caused by repetitive microtrauma — the longest toe repeatedly striking the front of the shoe during downhill running or prolonged athletic activity. This typically affects the first or second toe, depending on which is longest. Tight or improperly fitted athletic footwear is a primary contributing factor. Unlike acute trauma, runner’s toe develops gradually and may not be painful.
When to See a Doctor
Seek evaluation for a black toenail when: the pain is severe and limiting weight-bearing; the injury involved significant force (possible underlying phalanx fracture); the dark pigmentation appears streaky or irregular (melanonychia striata — may indicate subungual melanoma rather than hematoma); the discoloration does not grow out with the nail over 2–3 months; you have diabetes or peripheral vascular disease (any nail trauma can become a wound complication in high-risk patients); or the nail is partially detached, contaminated with debris, or shows signs of infection. An X-ray at the time of injury is recommended to rule out distal phalanx fracture whenever significant trauma is the mechanism.
Treatment
For a painful acute subungual hematoma, trephination provides immediate relief — a small hole is made through the nail plate (using a heated electrocautery device or a needle rotated through the nail) to allow the pressurized blood to drain, instantly relieving the throbbing pain. This is a painless in-office procedure done within 24–48 hours of injury when the hematoma is still liquid. After trephination, the nail is protected with a dressing. The nail typically remains attached and grows out normally over 3–6 months. When the hematoma involves more than 50% of the nail plate or is associated with nail plate avulsion (the nail has been torn away), the nail bed may have a laceration requiring repair — the nail is removed, the nail bed sutured, and the nail replaced as a biological dressing. For runner’s toe, treatment focuses on footwear modification — ensuring adequate toe box depth (at least 12mm) and leaving a thumb’s width of space between the longest toe and the front of the shoe.

Frequently Asked Questions
Will I lose my toenail after a subungual hematoma?
Many subungual hematomas resolve without nail loss, particularly if trephination is performed promptly and the nail bed is intact. However, when the hematoma is large (involving more than 50% of the nail plate) or when the nail is mechanically disrupted, nail loss is common. The nail typically detaches 3–6 weeks after injury as the new nail grows from beneath and pushes it off. The new nail grows in fully over 6–12 months. In most cases, the new nail looks normal.
How do I know if my black toenail is from injury or something more serious?
A traumatic subungual hematoma has a clear cause (recent injury or running), fills a large portion of the nail uniformly, and grows out with the nail over months. Subungual melanoma appears as an irregular, streaky dark band (melanonychia striata) that does not grow out normally, may extend onto the surrounding skin (Hutchinson’s sign), and has no clear traumatic cause. Any dark nail pigmentation without a clear traumatic cause, particularly in a single streak pattern, should be evaluated by a podiatrist or dermatologist for biopsy consideration.
How do I prevent runner’s toe?
The most effective prevention for runner’s toe is proper shoe fit: choose running shoes with adequate toe box depth (at least 12mm of clearance above the longest toe) and a thumb’s width of length beyond the longest toe. Trim toenails straight across, keeping them short but not so short that they become ingrown. Moisture-wicking socks reduce friction. Lacing techniques that pull the heel back in the shoe (heel-lock lacing) prevent forward foot slide during downhill running. Replace running shoes before the midsole compresses — typically every 400–500 miles.

When Toenail Issues Become Medical Emergencies
Most toenail problems are cosmetic or mild — but a few warrant urgent podiatrist attention: any black streak that wasn’t caused by trauma (rule out subungual melanoma), rapidly spreading redness (cellulitis or paronychia), throbbing pain that wakes you at night (possible infection or ingrown nail), and any toenail issue in a diabetic patient. We see same-day appointments at Balance Foot & Ankle for these red flags.
For chronic fungus or thickening, FDA-cleared in-office laser treatment now achieves clear-nail rates of 70-80% with no oral medication side effects. Most patients see visible improvement within 6 months.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
