Vibrations are one of my triggers too. All of the things mentioned above...even when I was in a wheelchair...the vibrations from the chair would just escalate my pain. Don't see myself ever getting one of those scooters because the vibrations from it would probably send me over the edge. I have found that if i keep my RSD leg up off the ground when sitting in a car, boat, etc then it's a little better. Doesn't help my upper body RSD but hey...any help is better than none.
