A felon is an infection of the fingertip. It’s usually caused by bacteria that get under the skin from an injury. This can happen from something like a splinter or if a tiny glass shard pokes the skin. It can cause pus to build up in the fingertip (abscess).
A finger felon can cause severe, throbbing pain that starts suddenly. Your fingertip may be red and swollen. Your doctor may drain the abscess. This is called an incision and drainage. It may also be treated with antibiotics and warm finger soaks. Your doctor may also ask if your tetanus vaccine is up-to-date. It’s important to treat a felon injury early so the infection doesn’t go deeper.
Home care
-
If you are prescribed antibiotics, take them exactly as directed. Finish the entire course of the medicine, even if your finger feels better. Don’t skip doses.
-
Care for your wound as directed by your doctor. This may include washing the finger with clean, running water. Cover the wound with a nonstick bandage or loose gauze.
-
Prop up your hand on pillows, several towels, or a cushion when possible to reduce swelling.
-
You may use over-the-counter pain relievers such as ibuprofen or acetaminophen unless your doctor has prescribed a different pain reliever. Don't take over-the-counter pain relievers without first talking to your doctor if you have kidney or liver problems, stomach ulcers or bleeding, or if you are taking blood thinners.
Follow-up care
Follow up with your doctor, or as advised.
