@donsbaby2016 I also have TOS and my hands used to turn blue and get cold and I could generate pain and spasms with my head and neck position. Myofascial release has helped me a lot. Can you share some more details or what your doctors have said you should try for treatment? MFR has given me better posture and helped TOS significantly. Here is our discussion where you can find more information. I'll be happy to answer any questions. https://connect.mayoclinic.org/discussion/myofascial-release-therapy-mfr-for-treating-compression-and-pain/
