Since I've been diagnosed for three years, and even beyond that, I've had this off and on pain under my left rib cage that sometimes go to my back. Some of you have described this feeling of a golf ball. Do you mean that it just feels like something is in there? Or do you actually feel a bump or a knot in there? I have had an US, CT scan and a gastroscopy which nothing has showed up on any of these. My labs are all normal. I just wonder if what I have been feeling for years is this hug. When I think of a hug I think of a squeezing sensation...don't know if I could describe it as that. My colon is sluggish much of the time...constipated. I am planning on getting that magnesium and starting that in a low dosage.:
