question: HiAfter taking antibiotics for almost a week (cipro 500mg) i have been having this slight but very bothersome pain in my abdomen mainly in my left and right side. my stool became loose and notice pieces of red stuff. I have ben like this for about a week. I had a colonoscopy and result was hemorroids easy to read. I prescribed my self the antibiotics so probably took it for nothing. At somepoint my stool was green but is getting less green. can this antibiotics cause all this. Thanks for any help
