after dealing with TOS for about a year and half now i have realised this, static postures and repedative anterior movements cause pain. I met one other person in my city who had TOS, he was a massage therapist for many years and as a result he got TOS. he told me it took 9 months off no work and treatment to get back to a point where he could work again.. So think at some stage i might have to bite the bullet and not work at all and really combat this thing once and for all.
