I have been diagnosed with osteoporosis several years ago. I ve been taking Evista for this. The osteo is mainly in my lower spine and left hip. Recently, within the past 2 or 3 months, I ve been experiencing significant pain in my elbows, upper arms, knees and thighs. It s getting to the point where just performing normal daily activities is so painful, I m not certain if I can go on like this. I understand that Evista may cause musculoskeletal pain, which I did experience when I first started using this medication, however, this is different.
