If a patient has symptoms of a separated nail bed, treatment should first distinguish which condition is causing the problem and then provide targeted treatment. If the separation of the nail bed is caused by trauma, common factors include frequent contact with irritants, such as nail polish and detergent. In this case, you need to pay attention to prevent the affected area from bleeding and use iodophor to disinfect it to avoid infection, and then wait for the new nail to grow out. If the nail is caused by a fungal infection, i.e., gray nail, the patient needs to be treated with antifungal infection, which requires oral spironolactone and then topical erythromycin cream. So once the nail bed of the nail is separated, the patient should first go to the hospital for a fungal test and then treat accordingly according to the cause.
