How do i treat an infected hang nail?

Antibiotics Needed: You get in to see your doctor and get on antibiotics.

See answer: An infected nail (paronychia) most often needs antibiotics and can require surgical attention if ingrown. Best wishes.

And maybe removal: In addition to dr killian's recommendations, sometimes hangnails or ingrown nails need to be partially or totally removed for healing to occur.

See below: Most of the time, they will heal by themselves. Sometimes, the infecction will be more serious and need antibiotics. You can soak it in warm water 2 or 3 times a day for about 10 minutes or so. If the redness, swelling and/or pain starts to get worse, go see your doctor.
