Ingrown toenails occur when the borders of the nail grow into the flesh on the sides of the toes. This may be painful and/or inflamed with redness, foul odor, drainage, or warmth. This may have been caused by heredity, injury, certain shoes, or cutting of the involved nails too short. There may be bone spur under the nail.
Home treatment would be proper trimming of the nail and soaking in warm, soapy water 1-2 times a day for 10-15 minutes followed by an antibiotic cream. If this does not resolve the problem, or if you have a history of peripheral vascular disease (circulation problems) or diabetes (peripheral neuropathy), you should not attempt to treat the problem on your own. Professional care will either be trimming and wearing wide shoes or removing all or part of the toenail on a temporary or a permanent basis.
Ingrown toenail problems are usually easy to clear up. If you have any questions regarding this sort of problem, ask your podiatrist.
