Onychomycosis is a common fungal skin disease that can be cured. However, it is essential to fully cooperate with the doctor's treatment plan. Currently, the treatment options for onychomycosis primarily include topical medications, oral medications, and physical therapies. For mild cases of onychomycosis, topical medications can be applied directly, or physical treatments such as nail trimming can be used. For more severe cases, oral medications are necessary, along with physical treatments like nail removal.
