DL... Can you reword the bed maneuver you explained? I can't visualize it, sorry. I am a firm chiropractic believer and went religiously until finances got tight. Kids also!
I agree with DL, it sounds like a misalignment causing a pinch. I am Day 9 of my fast and a old rhomboid/mid back injury that chiropractic care alleviated has been "pinching" and flairing up a little today but I am attributing that to the healing from the old chronic trama I dealt with before I sought chiro help.
Hope the stretches help and good luck!
