just had a thought - to take the edge of, did your Dr mention if the was a sensory centre/room in your area. We have one which was created for the disabled, but welcomes all comers and it's great gifties to exert some control over their environment. It may be beneficial for him to burn off some steam in a new environment - even if it's just for fun. My DS who has no issues yet loves it, my DD who is sensory seeking with a few physical over excitabilities is a different kid after going for half an hour - just relaxed.
