I would agree with D3m3nt3d. I have a keen interest in shoulder and knee injuries as i've had my fare share of them over the past few years, and I've only heard of the prob that u describe with your shoulder once or twice. Most likely if you get a chiropractor that is able to do this, you'll have to go back more than once. I would also recommend alot of stretching for your shoulder (as long as its relativley pain free...) as that could possibly help you out, good luck....
