Having had upper back pain and other upper back sensations for over two years this is my very simplistic take on this. I believe all this Pain in your back, feet, legs and arms etc is due to chronic/persistent muscle tension, driven by anxiety ( call it fear if you wish). You may not feel anxious all the time, but it is your current anxiety that starts the muscle tension and then it becomes habitual for the muscles to remain tense, causing pain, tightness, tingling and other sensations. I have tested this time and time again by noticing the difference and reduction in symptoms if I take a lorazipam (Ativan) tablet or to a lesser degree, if I consume alcohol. Both I believe are muscle relaxers? I know other TMS conditions may not be associated with voluntary muscle groups, I am convinced muscles tension is involved in all cases. Any thoughts on the anxiety/ muscle tension as a simplistic view of what causes TMS symptoms?
