Thank you for your input, Rachel. I believe I have found the diagnosis to my problem. The video link you provided touched on it, but a book I read recently by Dr. John Sarno hit the proverbial nail on the head! Tension Myoneural Syndrome precisely describes my symptoms. It all makes perfect sense to me. Now that I have identified the problem and its cause, I believe by following Dr. Sarno’s program I will be able to resolve my pain completely. The brain is a mysterious thing.
