I have been taking Tamoxifen  for about three months. I soon got intense pelvic pain, not unlike severe period pains, as well as moderate ‘flashes’. I can deal with the flashes by taking the Tamoxifen at night, but the pelvic pain has proved to be a real problem. My GP gave me a muscle relaxant that worked for a while but now it looks like I’m going to have to up the dose and I’m reluctant to take multiple pills at the same time, including Paracetamol, which isn’t very effective. Has anyone else experienced this side-effect and, if so, how did you deal with it?
