A Rip in the Skin From Tearing Off a Hangnail
The Rx: This can lead to paronychia, an inflammation of the skin surrounding the edge of the nail, and possibly to infection. To prevent infection and soothe soreness, soak the finger in a solution of one teaspoon white vinegar and four ounces warm water for three to five minutes, suggests Ronald R. Brancaccio, a clinical professor of dermatology at the New York University School of Medicine, in New York City. Do this twice a day for three to seven days. After soaking, apply a topical antibiotic ointment and a bandage to protect the area. If you develop swelling or a puslike discharge after 48 hours, see a dermatologist.
Quick camouflage: Apply a dab of liquid invisible bandage to form a protective barrier over the wound.
