I highly recommend "Treat Your Own Neck," by Robin McKenzie. It's available through Amazon and is part of a series by McKenzie. Having a pinched nerve in my neck led to not only chronic neck and shoulder pain, but constant headaches. My doctor recommended physical therapy and although I was at first reluctant (doesn't everyone who goes to PT either go forever or have the same problem as soon as they stop?), I did end up going. The PT is actually who recommended this book to me, and I've lent to several folks since then. Great exercises to not only alleviate pain, but keep it fron coming back.
