There is no clear and fast treatment for onychomycosis, and common treatments include medication, surgery, physical therapy and so on. 1. Medication: topical iodine such as povidone-iodine and ichthyol ointment can be used as prescribed by the doctor to help control the infection; if necessary, antibiotics such as oral amoxicillin can be taken to control the inflammation. 2. Surgical treatment: If abscesses appear, the pus can be drained through surgical incision, and nail correction surgery can be performed if necessary. 3. Physical therapy: Physical therapy through ultra-short wave, infrared and other methods can promote blood circulation, conducive to tissue healing. It is recommended that patients with onychomycosis go to a regular hospital in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor, so as not to delay the disease to bring adverse effects on the body.
