If the effect is not obvious after anti-infection treatment, surgical removal of the ingrown nail can be considered, usually under local anesthesia or nerve block anesthesia for local disinfection, the ingrown nail will be removed, and the nail bed under the ingrown nail will be scraped off, no more nail growth will occur in this area, and there will be no growth into the surrounding soft tissues, and the redness, swelling and pain related performance can be effectively relieved. In addition, it is important to change the medication once a day to prevent the aggravation of local infection and to promote healing.
