Canker sores and furuncles refer to a group of infectious skin disorders similar to the modern medical concept of folliculitis, boils, and carbuncles, where the infection ranges from superficial to deep and from small to large in scope. The treatment plan for these diseases is relatively similar. When they do not break out and do not completely suppurate, the choice of antibiotics, either intravenous or oral, followed by topical antibiotic creams, such as amoxicillin taken orally and then with mupirocin ointment applied topically, will gradually improve the symptoms. If there is pus and rupture, it is best to cut and drain the pus, and after releasing the pus, then antibiotic type of treatment can play a rapid recovery role.
