Nail pain is most often caused by onychomycosis. Inguguinitis is a common surgical infection, for this condition, in addition to the application of sensitive antibiotic treatment, such as azithromycin, cotrimoxazole, levofloxacin, and for those who do not have a history of penicillin allergy, you can use cephradine capsules, cefixime and so on. In addition, the local area can also be soaked in warm water with potassium permanganate, sterilized with iodophor, and then externally coated with Bactroban or ichthyol ointment. If there is no obvious symptom of localized pus, needle bloodletting therapy can be used, and if there is pus formation or conservative treatment is ineffective, then surgical treatment should only be considered.
