An ingrown toenail — onychocryptosis, if you’re collecting words — happens when the edge of the nail grows into the skin beside it. It starts as an annoyance and, left alone, can end as an infection. The good news: every stage has a clear fix, and the recurring kind can be ended permanently in one short office visit.
The three stages
- Stage 1 — irritated. The skin beside the nail is red, swollen, and tender to the touch. No infection yet. This stage is home-treatable.
- Stage 2 — infected. The skin bulges over the nail edge and may ooze clear fluid or pus. Warm soaks help, but the toe usually needs professional care.
- Stage 3 — chronic. The body tries to heal around the intruding nail and builds heaped-up red tissue (granulation tissue) that bleeds easily. This always needs treatment in the office.
What you can safely do at home (stage 1)
- Soak the foot in warm water for 15–20 minutes, two to three times a day.
- Lift the edge. After each soak, tuck a small wisp of cotton or waxed dental floss under the ingrown corner to guide it to grow above the skin. Replace it daily.
- Protect. Apply an antibiotic ointment and a bandage.
- Give it room. Open-toed shoes or a roomy toe box until it settles.
- Manage pain with over-the-counter relievers if needed.
Improvement usually starts within a few days. If it isn’t clearly better in a week — or if pus or spreading redness appears at any point — stop and book a visit.
How we fix it in the office
For an infected or recurring nail, Dr. Ahn numbs the toe with local anesthesia and removes only the offending sliver of nail — a few minutes of work, and you walk out.
For nails that keep coming back, the permanent fix is a partial matrixectomy: after removing the ingrown edge, the tiny strip of root cells that produced it is deactivated so that edge simply never grows again. The nail regrows slightly narrower, looks natural, and the problem is over for good.
Prevention, in one paragraph
Trim nails straight across rather than curved, don’t cut them shorter than the tip of the toe, and wear shoes that don’t crowd the toes. If your nails are strongly curved by nature, no trimming technique fully protects you — that’s the case where the permanent fix earns its keep.
