It was pretty clear what was wrong because I could hardly bend my head forward and down. This was due to the weakening of my upper back and neck muscles over a long period of time. I avoided working them out because it always felt wire and bothered me. Turns out that feeling was due to poor posture and my CT junction being very off and not aligned. The PT has had me strengthen my CT junction mobility and neck and back muscles. Lots of exercises with small weights (Ys, Ts, and Ls), band pull aparts, planks, anything that strengthens my neck/back and corrects posture is good. When my posture has gotten better and stronger, my chest symptoms and others have subsided. I did PT for 2 months and now feel a lot stronger and know what exercises to keep doing, it has helped tremendously. So please go to PT if you haven’t already and have them check your CT junction.
