I'm having some problems with both bowel and bladder, and wondered if they might be connected to taking Metformin. Basically, something seems to be making my bowel open and make a movement , and its happening literally every few minutes. I get the sensation that the bowel is about to open, then it does, and i usually pass a puff of wind to relieve it. This then actually leaves a sharp pain in the anal area for about 15 seconds, I wait a few minutes and it starts all over again. also, i hazve trouble passing urine - i can do it sitting down, but the "pushing" motion once again opens the bowel, and i can only then pass the urine once that process has finished. I had this condition about 6 weeks ago, stopped taking metformin for about 2 weeks until i was able to resolve the problem by having an enema in hospital - basically, a good clear-out. I resisted going back on metformin, as i suspected that may be a cause, and the symptoms if this recent flare-up began about a week after i started on the meformin again. I've got painkillers, which help for about 4 hours at a time, but even then I can't sit comfortably as there is the sensation of "something" in the anal area. Has anyone experienced anything like this possibly caused by Metformin - I've stopped taking them again, but the problems still remain. Doctor is having me in for blood tests, but in the meantime I literally can;t function - not when you're bowel is wanting to make a motion every few minutes.
