Thanks for the link

. My son has had RSDS twice so I am familiar with it. He has aspergers and his nervous system operates differently. He had it the first time after he was immobilised because of hip problem at 13 and second time sponataneously due to leaning on his arm for too long at
16. The first time I had to take him back into hospital to manage his pain but leant that was a waste of time. I then had to be tough and keep him moving through it. Magnesium and heat packs helped. I used lots of distraction whilst movie i.e the shops, reduced his stress by dropping a subject at school and I bought totum tennis. I don't think it is that. I don't have the level of pain he had nor have I had any injury or immobility.
