"i have been on bactrim for 5 weeks now and today i decided to stop taking it due to the side effects i&#039;m experiencing. my gums have become inflamed and have a burning sensation that is very bothersome. my face also feels somewhat numb and tingly. i&#039;m disappointed that i can&#039;t tolerate this medicine because it really did start clearing up my moderate acne problem. i would recommend giving bactrim a try..it just didn&#039;t agree with me."
