For the last few months I have had this feeling like there is something stuck under my right rib, like a tennis ball or wadded up sock, and it is really starting to annoy me. At first I thought I had strained a muscle b/c I had been working out in the yard the day before it started. It doesn't hurt, it just feels like there is something there that shouldn't be, but when I touch the area there is no swelling or bulge. After about 3-4 weeks when it wasn't going away I went to see my doctor. They did blood work, urine labs and sent me for an ultrasound of gallbladder, all came back normal. I have no other symptoms like nausea, vomiting, loss of appetite, etc. just this feeling like something is there. It seemed to go away on it's own and then came back and has come and gone since, sometimes lasting a few days, sometimes a few weeks. It seems to be more pronounced in the afternoon/evening and when I am sitting. It is also irritated by wearing a bra. The only other symptoms I have had that I think are related are these: A few months before this started I experienced a fluttering sensation, almost like when I was pregnant and the baby moved, in the same location, below the right rib. Since this has started, on 3 or 4 different occasions, I have also experienced a charlie horse like spasm in the same area, below the right rib, when bending over from a sitting position. Does anyone have any answers as to what this might be? I read somewhere that it could be Hepatic Flexure Syndrome which falls under IBS. Anyone else experiencing this?
