Hi Matt, Welcome.
There are many people here who can relate, myself included. One resource that may be of some use is
The Intractable Pain Patient's Handbook for Survival. You'll find many more resources in the
Chronic Pain forum. There are also forums for
Spinal Disorders & Back Pain and
Thoracic Outlet Syndrome.
Take some time to look around, and if/when you're ready to "talk", post something. If you need help in finding a local group, we may be able to help there too.
Best wishes,
Doc
