The patient with an ingrown toenail managed it themselves, requiring minimized activity and elevating the foot to promote local circulation. Additionally, topical disinfectants such as iodine tincture can be used, not merely applied, but used for moist dressing. Take some cotton soaked in iodine tincture and apply it to the swollen area around the nail fold, generally recommending a five to ten-minute application. Antibiotic ointments can also be applied externally, such as mupirocin cream. After application, cover it for two hours, and treat it two to three times a day. If this method does not effectively alleviate the pain, consider taking antibiotics that have previously caused no allergies, with a preference for cephalosporins or penicillin-type antibiotics. If the antibiotics still do not effectively relieve the pain, it is advised to seek medical attention at a hospital. (Use medications under the guidance of a doctor.)
