HelloI was wondering if IBS could cause a glof ball sized lump in the lower right abdomen. I am waiting for an appointment with my gastro in a few days, but of course I'd liek to get some opinions first.It feels like a slightly burning sensation and I can feel a lump there. Its been going on a few days and doesn't appear to always be constant although sometimes its worse than others. I have been having a well formed but large BM every morning with some minor straining. I am wondering if perhaps this is caused by an intestinal spasm that is occuring in that area and its either gas or maybe stool that gets stuck there and is eventually released, the lump feels kinda hard to be gas but who knows. Anyone have any ideas?
