I ve been taking cephalexin for 2 months straight, then had a month long break from it, after which, my body has been aching badly. The reason I was taking the antibiotics was for a schmorls node in my lower back. My worry is contracting c.diff if I take any more of them, and I wanted to know the likelihood of contracting c.diff from prolonged antibiotic use, as I m also taking dexilant for my GERD, and I read about gastric acid being a factor. Is there any kind of antibiotic that can help with lower or no risk or getting c.diff?
