I have a ingrown toenail and it hurts badly. what can i do?

See Podiatrist: To get proper evaluation and treatment. This will require ingrown portion of nail to be cut out. In the mean time, try soaking and apply antibiotic cream/ointment. If ingrown is superficially and can be easily cut back, you can do this yourself but is deep nor difficult to do, get medical attention.

Nail care: Ingrown toenails can be 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. One should always try to cut the nails strait across to avoid leaving an embedded nail spicule. If pain or redness continues get it looked at by a professional.
