The most important clinical decision with Ingrown Toenail isn't which treatment to start with — it's which subtype or underlying cause you actually have. Our podiatrists regularly see patients who've been treated for months for the wrong diagnosis. The correct identification changes the entire treatment path. Call (810) 206-1402 — Dr. Tom evaluates this condition at both Howell and Bloomfield Hills locations.
What Causes an Ingrown Toenail?
An ingrown toenail — technically called onychocryptosis — develops when the edge of the toenail (most commonly the big toe, or hallux) grows downward and into the soft skin of the nail fold rather than straight forward over it. The penetrating nail edge acts as a foreign body, triggering inflammation, then pain, then infection as bacteria colonize the disrupted skin. Left untreated, the infection can spread to the surrounding soft tissue (paronychia), producing pus, proud flesh (hypergranulation tissue), and in diabetic or immunocompromised patients, a potential entry point for serious limb-threatening infection.
In our clinic at Balance Foot & Ankle, ingrown toenails are one of the most common presentations we see — and one of the most permanently treatable. A simple in-office procedure resolves the problem definitively in the vast majority of patients. The most important message: do not keep tolerating a recurrent ingrown toenail when a 20-minute procedure can prevent it from ever coming back.
The main causes we identify include:
- Improper nail cutting: Cutting nails too short, rounding the corners, or cutting down into the nail grooves leaves a sharp nail spicule that penetrates the skin as it grows forward. Nails should be cut straight across, leaving the white free edge visible.
- Tight or narrow footwear: Shoes with a narrow toe box compress the nail folds against the nail edge, forcing the nail into the skin. This is a major factor in adolescents and athletes wearing cleated or tight athletic shoes.
- Naturally curved or involuted nail shape: Some individuals inherit a nail plate that curves sharply at the edges (involuted or pincer nail) — the nail's geometry makes ingrowth biomechanically inevitable regardless of how carefully it is trimmed.
- Trauma: A direct blow to the toe, stubbing the toe, or repeated microtrauma from running causes the nail to grow irregularly or stimulates the surrounding tissue to hypertrophy around the nail edge.
- Hyperhidrosis (excessive sweating): Moist, macerated skin in the nail fold is more easily penetrated by the nail edge and is slower to heal once violated.
Staging: How Bad Is Your Ingrown Nail?
We use a three-stage classification to guide treatment decisions:
- Stage 1 (Inflammation): Erythema (redness), mild edema, and pain on pressure at the nail fold. No drainage. The nail has not yet fully penetrated the skin. Home care is appropriate at this stage.
- Stage 2 (Infection): Purulent drainage, increased edema and erythema, and formation of granulation tissue (proud flesh) alongside the nail edge. Bacterial infection is present. Professional removal of the offending nail border is required — home care will not resolve an infected ingrown nail.
- Stage 3 (Chronic change): Marked hypertrophy of the nail fold with abundant granulation tissue, often partially overgrowing the nail. Chronic recurrent infections. Permanent surgical resolution (matrixectomy) is the appropriate definitive treatment at this stage.
Home Care: What Is Safe and What Is Not
For a Stage 1 ingrown nail (no infection, no drainage), home care is reasonable for 2–3 days while symptoms are mild:
- Warm water soaks with Epsom salts 2–3 times daily for 15 minutes soften the skin and nail, reducing the pressure and discomfort
- Cotton or dental floss wicking — gently lifting the nail edge from the skin fold with a small piece of cotton or waxed floss placed under the nail corner — can relieve the ingrowth in early Stage 1 presentations
- Properly cut the nail: Trim it straight across, not curved, leaving the edge above the tip of the toe
- Wear open-toed or wide toe-box footwear to eliminate nail fold compression
What to avoid: Never attempt to dig out an infected ingrown nail at home — this invariably creates a deeper wound without resolving the nail spicule and risks spreading the infection. Never use hydrogen peroxide on the open nail fold (it delays healing). Never use “ingenious” home methods like cutting a V-shape in the nail center — this is a myth that does not change nail growth direction and has no clinical evidence.
⚠️ Do not attempt home care — see us immediately if you have:
- Pus or purulent drainage from the nail fold
- Red streaking spreading up the toe or foot from the infection site
- Fever or chills in association with toe pain
- Diabetes, peripheral neuropathy, or peripheral arterial disease
- Symptoms persisting beyond 3 days of home care without improvement
- A third or subsequent recurrence on the same nail
In-Office Treatment: Nail Avulsion and Matrixectomy
Professional treatment of ingrown toenails in our office is quick, highly effective, and performed under local anesthesia — patients typically leave walking normally and return to regular shoes within 24–48 hours.
Partial nail avulsion (for acute or first-episode cases): After digital block anesthesia, the offending nail border is separated from the nail bed and removed from the nail groove under direct visualization. This immediately removes the nail spicule that is penetrating the skin. The wound is dressed and the patient leaves without sutures. For first-episode infections without a strongly involuted nail plate, this alone — combined with proper nail trimming education — may prevent recurrence.
Partial nail matrixectomy with phenol (permanent treatment): After removing the nail border, the nail matrix (the growth cells at the nail root) corresponding to the removed border is destroyed with a controlled application of 88% phenol solution. This permanently prevents regrowth of that portion of the nail edge, eliminating the structural source of recurrence. The remaining central nail continues to grow normally; the permanent narrowing of the nail is usually cosmetically imperceptible. This is our preferred procedure for any recurrent ingrown nail or for an involuted nail anatomy where recurrence is biomechanically inevitable. Recurrence rate after phenol matrixectomy is approximately 5% — compared to 50%+ after simple avulsion alone.
Total nail matrixectomy (for severely deformed or thickened nails): When the entire nail is involved — severely involuted pincer nails, mycotic nails with full-width ingrowth, or Stage 3 presentations with complete nail fold overgrowth — total nail removal with complete matrix ablation eliminates the nail permanently. This is the appropriate procedure for patients who have had the entire nail repeatedly ingrowing or who have nail deformities that make regrowth of any portion problematic.
Recovery
Following phenol matrixectomy, the treated area produces a controlled chemical wound that heals over 2–4 weeks with twice-daily wound care (soaking + antibiotic ointment + dressing change). Most patients return to work the same day or the next day in open-toed footwear. Athletic shoes are typically tolerable within 48–72 hours. During the healing period, a mild serosanguineous (yellowish) drainage from the nail groove is normal and expected — it is the phenol wound healing, not a sign of infection. True infection is uncommon after properly performed matrixectomy but is characterized by increasing (not decreasing) pain and purulent (thick white/green) rather than serosanguineous drainage.
Ingrown Toenails in Diabetic Patients
Any ingrown toenail in a patient with diabetes, peripheral neuropathy, or peripheral arterial disease is a medical urgency, not a minor inconvenience. The combination of reduced infection-fighting ability (hyperglycemia impairs neutrophil function), impaired sensation (neuropathy that prevents pain from signaling the severity of infection), and poor wound healing creates conditions where a seemingly minor infected ingrown nail can progress to osteomyelitis, gangrene, and amputation with frightening speed. Diabetic patients with ingrown toenails should be seen within 24–48 hours. Home treatment is not appropriate for this population.
Frequently Asked Questions
How long does ingrown toenail removal take?
The in-office procedure takes approximately 15–20 minutes from anesthesia to dressing. Patients walk out under their own power. Local anesthesia makes the procedure comfortable — most patients are surprised by how painless the experience is once the anesthetic is in place.
Will the nail grow back after matrixectomy?
After partial phenol matrixectomy, the narrow treated border does not grow back in approximately 95% of cases. The central portion of the nail grows normally. After total matrixectomy, no nail regrows.
Can I prevent ingrown toenails?
Trimming nails straight across (never curved), wearing shoes with adequate toe box width, keeping feet clean and dry, and avoiding repetitive toe trauma (in runners: properly sized shoes with adequate toe room) significantly reduces risk. For patients with an anatomically involuted nail, preventive matrixectomy before the nail becomes infected is a reasonable discussion.
The Bottom Line
Ingrown toenails are among the most treatable conditions in podiatry. An infected ingrown nail at Stage 2 or 3 warrants professional care — home care cannot resolve the nail spicule. Phenol matrixectomy permanently prevents recurrence in 95% of cases and is performed in under 20 minutes in our office. If you have had the same nail ingrowing repeatedly, or if your ingrown nail is currently infected, do not keep suffering — call us for a same-day appointment.

When should an ingrown toenail be treated by a doctor?
See a podiatrist immediately if there are signs of infection: increasing redness, warmth, swelling, pus discharge, or red streaking up the toe. Diabetics and patients with poor circulation should see a podiatrist at the first sign of any ingrown toenail — infection can escalate rapidly in these populations. For non-infected ingrown toenails, see a podiatrist if home care fails after 2–3 days or if pain limits normal activity.
Can I fix an ingrown toenail at home?
Mild ingrown toenails without infection can be managed at home: soak in warm soapy water 15 minutes twice daily, gently lift the nail edge and place a small wisp of cotton underneath to redirect growth, and wear open-toe or wide-toe-box footwear. Never cut a V-notch in the nail — this is a myth. Do not attempt home treatment if the area is infected or if you have diabetes, neuropathy, or poor circulation.
Will an ingrown toenail go away on its own?
Mild ingrown toenails may improve with conservative home care if the offending nail edge is redirected before it penetrates the skin. Once the nail has broken through the skin and an infection has developed, professional treatment is necessary. Without treatment, the infection can spread and become a chronic recurring problem requiring a permanent nail procedure.
What is a permanent fix for recurring ingrown toenails?
A partial nail avulsion with phenolization is an in-office procedure under local anesthesia that permanently removes the ingrown nail border. The podiatrist removes the offending nail edge and applies phenol to destroy the nail matrix cells, preventing regrowth. The procedure takes 15–20 minutes, has a >95% success rate, and requires only minor wound care during healing. Most patients return to normal footwear within 2–3 weeks.
The American Podiatric Medical Association notes that proper nail trimming technique and well-fitted footwear are the most effective ways to prevent ingrown toenail recurrence.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
The fastest safe relief for an ingrown toenail is soaking the foot in warm (not hot) water with Epsom salts for 15–20 minutes, 2–3 times daily — this softens the skin and reduces inflammation. Gently lift the edge of the nail and place a small piece of clean cotton or dental floss underneath to redirect growth. Avoid cutting the nail into a curved shape, which worsens ingrowth. Over-the-counter numbing agents provide temporary relief but do not fix the problem. If you see pus, spreading redness, or the area feels warm, see a podiatrist the same day — infected ingrown toenails require professional drainage and often a minor in-office nail procedure that takes under 15 minutes and provides lasting relief.
