I have not had much luck with Doctors and back problems, just got the "pain relief perscription" and never got them filled. My wife has the best diagnosis when she told me to start doing sit ups, that ever helped. I'm not familliar with your type of injury or the treament your taliking about but have you ever had "BodyTalk"? It was the immediate pain relief I needed several times over the years. My Aunt and Cousin are big time healers, it may sound all hocus pocus but it does work/ worked for me.

I think she is also a registered massage therapist and the treaments may be covered as part of your benefits package.
