I'm on day 20 with 400/80 bactrim 2x a day and I am having the worst cysts come up all over my cheeks and jawline. I didn't have any side effects other then breaking out worse. Is this normal should I stop the meds? I called derm which I'm not happy with and he says 20 days isn't long enough to see improvement but I need my face to clear before Christmas we are going back to my hometown. I also have been using retina mycro but stopped that cause I think that's what the problem is. Anybody else get worse before it gets better??
