Hi. I've been having worsening back pain for quite a while. I have had x-rays taken which show arthritis/degenerative disk disease. However, I'm not sure that's what's causing my pain. All of the pain is on the left side, and there is a lump on that side. It is in the spot where the pain is coming from. Perhaps it's a bone spur, but I'm not aware of any of them showing up on the e-rays. I can't seem to find any information on line regarding bumps that can be felt near the spine. Can anyone help me with this?
