Hi everyone. I am new to this forum. I'm 56 and was just diagnosed with osteopena and osteoporosis. My doc wanted to put me on Fosamax but my dentist warned me that due to boneloss in my jaw that it could cause necrosis of the jaw. So my doc started me on Evista which I started this morning. I weigh 138 and am 5'7". She didn't tell me that weight gain would be a side effect. She mentioned hot flashes. Yikes! So I'm glad to find your forum and hear your experiences. I watched my Mom become crippled by osteoporosis. By the time she was 68, she could barely walk. Has anyone noticed that exercise has helped increase bone density? Not crazy about side effects but willing to put up with some if it helps the bone improve. (May 2, 2009 | post #62)
