i can't tell you what it is either since i cannot examine the area. unfortunately your description is not specific enough to narrow down the many possibilities. my suggestion for you. since you have battled this skin affliction for four months now with various treatments. is to see a dermatologist for a higher-level evaluation. if you have seen a dermatologist then see a different one for a "second opinion". i am sorry that i can't help you but there is no substitution or a hands-on evaluation.
i don't think this is staph impetigo or dermatitis? . skin infection around corner of mouth and chin. i've had it for about 4 months. i've tried 3 ointments over the course of time but after a while per ointment it would seem okay and then it would become worse and unresponsive to the topical creams/gel. clindamycin phosphate mupirocin and ketaconazole. however the symptoms are the same:. red warm terribly itchy stinging crusting and dry without any application applied. i don't know what it is. only that it seems like a skin infection.
