Interesting. I had a C5/C5 compression and impingement issue and it has been heck to recover from. Caused a lot of issues in my tennis play because how it also effect rotator cuff and nerves, so I am starting down trying some of these things. Chiro firend mentioned the inflatable (he calls it the puff cuff) to start for stretching and releasing the pressure. Hoping I don't have to go to far cuz I have seen some of those $500+ crazy contraptions you strap your head in and it conorts you around.
