I am glad to hear you have found some relief with wearing a splint. Have you tried any muscle relaxers for your neck and back pain? I was having a lot of neck and shoulder pain, and I have had some relief taking a muscle relaxer called Zanaflex. I have also heard of people taking Flexaril. I didn't gain much relief from it. I don't know if this option will work for you. I am just throwing you an idea.

Should you feel happy? I don't know the answer to that; I am still trying to decide that question for myself. I keep clinging to the hope that maybe someday I will wake up and my symptoms will go away slowly but surely. I wish the same thing happens for you.
