Oh Yes.....can definety relate to this, i finished 5 years of Tamoxifen 2-3 years ago, I had gallstones 2 years ago, horrendous pain, I had a scan which confirmed them, and subsequently had my gallbladder removed afew months later, unfortunatey though I have fallen into the percentage who still get gallstone pain occassionaly even without the gallbladder!!
Also the legs too are a problem, ok walking on flat but uphill etc., legs competely seize up.
