Hi Old Guy,
Can I ask a question, is your wife's pain from crazy muscle tension (spasticity)? I have PPMS so I am familiar with locked lower body parts and nasty spasms. Has any one suggested Botox injections? I was getting them in my legs and lower back at 90 day intervals. I recently had a test done with a small dose of Baclofen injected directly into my Cord and the results were startling from spasticity reduction. I should be getting an Itrathecal Baclofen pump installed in a few months. They can play with the affected area some what with the height of the catheter in the Spinal Cord to a point. The company who makes the pump is called Medtronic and they have a referral service to a provider. The procedure is Medicare approved. There is plenty of info on the web about it. A great website for Spinal problems is CureCare from Rutgers Univ. FYI. Please feel free to PM me if you would like to talk some more.
All the best, Mark
