Yes, many people have complications with spine injections, and xray would not show a thing.
The MRI may show something -- let's wait and see.
In the mean time, ice treatment might be appropriate. What did your docs say?
MD thinks that the injection somehow irritated the nerves surrounding the area. I have been doing ice and heat, it only provides minimal relief. Swimming therapy in warm water pool feels awesome, I have fibromyalgia, while in the pool ALL of my pain is decreased significantly until I get out. I'm going to go to the pool more often. Had MRI yesterday so we shall see what MD says, thank u for responding to my post.
As I said, this is sometimes a consequence of epidural injections.
I hope the injury to tissue is temporary.
