i am so sry 2 hear bout ur son but what believer said was rite RSD can spread at any given time and at any rate it wants its a demon we all know. i wood call the dr agin if it gets worse or persists. i just cant imagine the dr woodnt want 2 c him after that. i had blocks for a year and a half they only helped for a very limited amount of time but its was better than nothing and works way better for most other people. i cant imagine how hard it is for u 2 make him play and keep moving but u r rite hwen u r rite when u know that it is a bad idea 2 just let him do nothing. i hope all gets better and keep me upfdated plz. i wish u and hijm and the rest of ur family all the luck in the world u r in my thoughts and prayers. i wish him all the pain free days in the world.
