If there is more local pus but a small blister, the doctor may use a sterilized instrument to puncture and suck the pus, and then apply iodophor, Bactrim, iodine and alcohol locally for anti-inflammatory treatment. However, if the abscess is large and there is a combination of redness and swelling, the abscess must be released by making an incision in the paronychium under local anesthesia and, if necessary, removing part of the nail to open up the wound to prevent the accumulation of pus, and after the abscess is released, regular dressing changes are needed to prevent re-infection. Cephalosporin or penicillin antibiotics can be taken orally during treatment. You also need to pay attention to your diet, not to eat too spicy food, not to drink alcohol, and to change the medication regularly in the injured area.
