Do you have diabetes mellitus
or hypertension? Before proceeding to remove more of the nail, complete blood picture, bleeding and clotting time testing should be done and diabetes or hypertension should be looked for. The ingrown part of the nail needs removal in order to avoid future infections. Any surgery performed on highly infected and inflammed tissues will result in improper and delayed healing. Hence antibiotics and thorough evaluation are necessary before attempting further surgery. Hope it clarifies!
