Hello all, I've been SMM for more than 5 years. I am beginning to have reoccurring back pain. I have upcoming appointments for Bone marrow and MRI. That said, I recently threw my back out and can barely move, walk, lay, or sit (don't know how I'm going to do these tests). I walk slowly around my home and am losing all muscle in my legs, arms, abdomen. Any recommendations for any exercise that doesn't cause added pain?
