Hi I wish I would have found you sooner I hope your son is ok. The number 1 place in the world you could take your son is the Environmental Health Center Dallas "EHCD" dr William Rea is the best in the world for this kind of problem. I suffer from very severe MCS & I would go there if I could afford it. Phone consultation with dr Rea aren't that much at all. I have a friend who started working for a pesticide company & a tank opened on his back and got all over him & he developed MCS. Hopefully your son is ok, good luck, Mario
