I have something going on in my shoulder too. My back goes out sometimes. I take glucosamine when I think about it and it really helps. When my back would go out I would go to the chiropractor and one treatment would do the trick, but my chiropractor retired (he was a cracker) and the new one only wants to use the thumper. It doesn't do anything for me. Most of the chiropractors here won't take you if you don't have health insurance, so I will have to keep looking.
