Does anyone else have this?? I have the worst and most odd sensation of tightness in my mid back. It feels like the muscles that run down my spine on each side of my spine get very tight and are actually squeazing my spine. And I also have a simular tightness on my side just under my rib cage that feels like its conected to the tightness I feel near my spine. Heat helps but as soon as I remove the heat, it comes back fairly quickly, its been here for months. Is this just anxiety or should I be more concerned about it being so chronic? I just dont feel like its anxiety, I have so many muscles in my head and neck and it goes straight to this site in my back. Its kind of a scary sensation, like I cant get away from it. Any clues or suggestions?? Thanks everybody
