Dear Linda C.
Sorry to hear about your pain. I am not sure what the pain specialist is telling you. Scar tissue adheres to the nerve or compresses by blocking the nerve exit from the foramen. A simple injection of saline, I don't think it would remove the scar tissue. But, I have not done this technique. I think I would get a second opinion about the procedure. I am not sure what to recommend as I do not know what your exam is like nor what the MRI shows. Most of the time we recommend vigorous rehab and PT for recovery. But your far enough away from surgery that it may not help too much at this point. Some recommend surgery to remove the scar tissue, but this is not always successful. Nerve blocks sometimes help as well as TINS stimulators.
I would get a second opinion before using the injection method mentioned.
Sincerely,
CCF Neuro MD
