I had multiple painful boils on my bottom for which I consulted a general physician and he put me on a 7 day course of amoxicillin and clavulanate antibiotic. All of them healed after the course was finished but after a few days one of them seemed to reoccur and seem to be sort of back to the same condition. It's just as painful and seems pretty red and swollen. Don't know what to do now. What could this be? Should I go to a general physician again or to a dermatologist? Help is really appreciated. Thanks.
