How is the best way to get rid of an ingrown toe nail ?

See a Podiatrist: It can be easily treated by removal after an injection of anesthetic.

Removal...: ...Is the only permanent solution. Just the painful border can be removed, or the entire nail if necessary. After removal you can let the border grow out again, or your doctor can use a chemical to stop the nail from regrowing. If you're concerned, don't perform bathroom surgery on yourself. That can lead to an infected ingrown toenail, which could require antibiotics.
