Thank you for your reply. Everything was just fine with me 6 months ago. I lost 20 pounds in a very short time. I was skinny before. I thought this happened because I recently found out that I have a severe osteoporosis and have a few spinal fractures and I thought that osteoporosis medication contributed a lot of pain as a side effect . I was very active before and I am in mid sixties. I been going to various doctors and nobody can explain why I suddenly got this debilitating pain all over my back. I am still able to walk but becoming harder and harder. Finally doctor who I been seeing for the last 3 months started taking about some muscle skeletal disorder. Without offering any solutions. I am going to seek a second opinion.
