I am looking for answers. I have been dx with arthritis in lumbar region 5 years ago.  Since then I have developed hard nots that hurt when touched, they seem to be on putting pressure on the spine, this of course is painful to sit, drive in care period of time. I was told they were fatty tissue, then calcium depsits. I give up
Hi and welcome to Chat Doctor. It can be fat deposit or calcium deposit but also your arthritis may be caused by autoimmune disorders, and then it may manifest with nodular subcutaneous lesions. Whatever it is, treatment is based on anti-inflammatory and steroid therapy administered orally or by injections. Certain exercise may help to but all this is degenerative process of aging. Wish you good health.
