Yes, I have been taking Tamoxifen for 2 years and have been in so much pain with my back both side of my back my right hip and pelvis, my bones ache and when I stand I can't stand up right without my back locks up on me, I do exercises to ease the pain. I use heating pad and stimulating machine once a day, and I have a foul odor when emptying my bladder. Hope you can help me, I'm in so much pain. Thank you. Lupe sanchez
