I agree with what Knot said above. I found that the injections I had caused worse symptoms afterwards, for up to 2 or 3 weeks, and then the pain and tingling in the right arm and hand would revert back to previous levels. They are designed to treat the symptoms only.

As far as pillows, the Mediflow water pillow works great for me. It is like a waterbed for your neck, and you can adjust the level of support by varying the amount of water. I have recommended it to 3 or 4 people who absolutely loved it. I have used it exclusively for over 5 years.

The McKenzie techniques were helpful to me, and there is also another book out written by 2 doctors about all the various treatment options which is very comprehensive:
