I was wondering if anyone has used clindamycin gel and have had any reactions from using it? I'm talking about the topical gel form. I was reading the possible side effects of clindamycin gel and it said it can cause stomach problems. I'm wondering if I should even be using it at all since I have IBS. I'm going to my doctor's this week and I shall ask her about this. I hate to say but I haven't had the best luck with doctors. Sometimes they have made me worst than better. That's why I'm asking everyone here. Thanks
