It's not so bad. I can control it ninety percent of the time. I don't break out either, it just HURTS. The only really bad problems I've had in the last year were yesterday (he had his arm around my shoulders and I got the strongest feeling of something biting the back of my neck and shoulders, like a horse fly, even though there was nothing there) and after the 24 hours on the airplane, a wool blanket the girl in the seat next to me was using rubbing my arm as she slept.
