It took 2 years before the fibrosis in my neck (from RT) got to the point where I was having fairly consistent neck spasms. I tried PT with limited success and now they just give me scripts for Valium. I would ask the techs about your neck position and the spasms - something is not right. Maybe they got the headrest backwards - they did that to me one time. In any case you shouldn't be having spasms this early in the game.
