Sounds similar to what I'm giong through - similar symptoms: Pain on the right side, just under my ribs. I've gone through an ultrasound, CT scan, blood tests for liver function and all came back normal. The pain has continued so this past week my doctor ordered chest and rib X-rays and I'll get the results on Monday.

If those are normal, my next step is to go back to my plastic surgeon as that's the side where I have the breast reconstruction after a mastectomy for breast cancer. I'm just hoping the cancer hasn't returned. I just want the pain to stop!

Get it checked out - you may learn that it's just gas, but you won't know if you don't ask.
