My 16 yr old son has had 2 episodes in 5 months where he loses the ability to move. He says it s like his body starts falling asleep, while he is walking, beginning with fingers and toes, but he stays awake. It lasts a couple hours and as he regains the use of his body he says it feels just like- when your arm is waking up after you have laid on it for a while. His fiends said he felt cold to the touch, but my son claimed he felt fine. He also has chest pains. I m thinking his Dr. is leaning towards severe depression, but I highly doubt it. He has had chest pains and weakness episodes long before he ever had to deal with anything stressful 7-8 yrs old.
