@amywood20 That sounds like good news. The shoulder injection should confirm it, if it is the source of inflammation. Inflammation from surgery definitely makes other places with inflammation worse and 4 months post op is when that happened to me too. The "shoulder neck syndrome" he describes sound like thoracic outlet syndrome to me which is what I have and that is what the MFR helps, and you don't have to do painful stretches for that, it's all manual therapy. If you don't improve, you may want an evaluation for thoracic outlet syndrome. It is common among spine injury patients and can be caused by a whiplash. I hope you'll check in and let me know how you are doing after treatment. Take care.
