Hello! Have you encountered fungal skin infection? It looks like in the photo only on legs. A dermatologist prescribed salicylic acid, iodine 2%, cream Teraflin and tablets I don't remember the name that needs to be taken with fatty milk. The course of treatment consists of 15 days. Three days have passed but there is no effect yet. The daughter cries so much, trembles from pain. Has anyone had this? When did it go away? After treatment, does it stop bothering?
