What to do if I have an ingrown toenail infected?

Evaluation. See a Podiatrist ASAP, as infection can worsen.
Have it evaluated. Ingrown toenails can be temporarily remedied through soaking your foot in warm water, removal of embedded debris from the nail borders, and applying an antibiotic ointment to temporarily soften the corners. If you have continued pain, redness or drainage, get it looked at by a professional as you may need to have the ingrown nail border removed and you may need antibiotics.
