As you're looking for a PT, the following credentials are good ones to look for as stand alones or in combination: OCS, COMT, IFOMPT, FCAMT. These are PTs with certification and testing in spinal biomechanics and treatment.

Also, consider trying to sleep in a recliner with a towel rolled up under your neck to support a natural curve. Arms on pillows to hold elbows out from sides a little and slightly in front of the line of your body. This can allow for better relaxation through the neck and shoulder blade areas.

I'm going to see if I can find some other links to help.
