If the swelling of the nail groove inflammation is not serious, you can apply anti-inflammatory drugs externally, such as iodophor solution, Pepto-Bismol, or use iodine to disinfect and then deiodize with alcohol, and at the same time, try not to move your fingers too much. With the prolongation of time, the inflammation can gradually subside. During the treatment period, you should not eat too spicy food, or drink drinks containing alcohol, etc. If the local swelling is serious, or even redness and oozing, then you need to go to the general surgery department of the hospital as soon as possible, or the hand and foot surgery department or emergency surgery department for disposal. The doctor will anesthetize the root of the finger, make a local incision to drain out the fluid, and at the same time may need to remove part of the nail, and need to make regular medication changes at a later stage. A small number of patients also need oral antibiotic treatment, commonly used drugs such as cephalosporin antibiotics or penicillin antibiotics.
