Ive gone to the gp several times and the acne goes away for 2 or 3 weeks but then comes back. Im on erythromycin 250mg gastro resistant tablets and ive been taking them for 3 months. Havent seen a difference but im supposed to take it for 5 or 6 months so i suppose i gotta wait till ive finished taking it. I really dont know what to do tho, i feel like if i go to the gp there just gonna give me something thats not gonna work. Plus my acne my back and chest have been really bad ajd get spots that hurt when touched.
