I don't know what a "Pro Adjuster" is, but I imagine it is a chiropractic treatment.
While chiropractic can be a harmless pursuit, some practitioners are very aggressive in their adjustments, causing muscle strain and other soft tissue injury.
A rough chiropractor can do more harm than good. If you wish to continue with chiropractic care, you might consider finding a gentler practitioner.
I had a similar happening....I also have a curve in my spine that has never given me a problem. ..I had 3 or 4 adjustments with the pro adjuster and by the last one I could hardly sit in my car to drive home. Each adjustment had made me worse and I would never consider allowing anyone to use the pro adjuster on me again. I had to call my medical doctor and was on muscle relaxers. It took me about a week to get straighten up...I was bent over with terrible spasms that traveled up my back and into my neck and back of my head. And every since this happened I from time to time will get the spasms and they will not go away without meds.
Did you ever get help? I have the same problem
