Have suffered off and on w/IBS, diverticulitis and diverticulosis, for years, and started having the problem you described a couple of years ago. Had all sorts of tests run, no real help. Until my husband mentioned my symptoms to a retired physician who immediately diagnosed splenic flexure and suggested Bentyl (generic is Dicylomine). I told my internist and he said let's try it, and it did help immensely. The 20MG I take only when needed makes me a bit sleepy, but it relaxes the bowel and relieves the pain. I also find, that as w/the IBS, etc., trying to keep a good diet (lots of fiber), drinking plenty of water, getting rest and hitting the gym, all help immensely. I really get into trouble when too stressed, off my diet or overtired. Really means a lifestyle change, paying attention to what causes the problem(s). Take care, hope this helps; sorry for your pain - I understand.View Thread
