If left untreated, nail infections can easily become infected and can lead to other diseases such as osteomyelitis. Once you encounter a purulent condition, it must be treated promptly. With septic nail infection, the first thing you need to pay attention to is self-care. The main task is to eliminate the inflammation and prevent infection. You can take oral antibiotics and scrub the affected limb with iodophor to prevent further infection; also pay attention to cleaning and daily care. In addition, some redness and swelling can be reduced by applying nail inlay cream. If the nail infection is more serious, the pus should be removed completely. If the pus is confirmed to have accumulated, you can choose to have an incision and drainage procedure. This is done by cutting the incision and squeezing out the pus, then disinfecting it properly and simply dressing it without closing the wound. If there is still residual pus, the wound will be allowed to cut open again, prohibiting it from healing. After allowing the residual pus to drain out and then disinfecting it thoroughly and dressing it completely, the rest is to wait for the wound to heal naturally.
