Dermatology. You may be helpful with Minocycline or other anti acne treatment , you should see deatologist.
See below. Bactrim (sulfamethoxazole and trimethoprim) can take care of some skin infections especially staph and strep but not all. See you doctor to get a culture of the infection so, if the bacteria is not sensitive, the culture can determine which is.
