I sure hope that fixes the problem for you. Sounds scary, but if they can perform the procedure and alleviate your pain that would be wonderful for you.

I have CRPS from a L5S1 injury in my lumbar spine, among other injuries. I have had at least 5 MRIs sincethen where they did not find any unnecessary fluid (all the MRIs were prior to my baclofen pump install).

I hope for you that everything goes well with the procedure. I'm sure your spirits have been lifted at the prospect of being rid of RSD/CRPS.
