About the same time DH fell off the roof, I somehow froze up my left shoulder. We had no income and no money so I had it real bad for about a year... I did all kinds of exercises, put cold compresses on. Suffered a LOT. Then I went to a chiropractor and she worked on it for a few months. When she worked on the very top of my neck it unfroze.
At the same time I had a close friend go through surgery for her shoulder. Mine now works. Her's does not.
I banged my head real hard at work a few months ago and it felt like my shoulder was freezing up again so I had my chriopractor adjust the top of my neck and it went away again. Then I remembered that I had banged my head real hard the first time I had it freeze up.
Very painful and very frustrating isn't it?
