Hi I have a sharp feeling pain in my bowel and stomach pain across my belly button line which comes and goes and I am taking tramadol for another complaint which is constipating me but think if I wasn't I would be permanantly running to the toilet, and when I do go I always feel like I need to go again and it is really smelly. Any ideas on what this could be as I do suffer from severe IBS and a diverticular disease and going through a lot at this time and always feeling stressed and anxios and worrying all the time.
