ok so I have a question!!!!

my son is a year old....well the last three nites he has been like twitching uncontroallby....he is a super big mama's boy and he didn't want me to touch him at all if I did he would scream bloody murder....his feet were ice cold and he was pale his pupils were big and he didn't even realize I was sitting there.....i have a video of it....we gave him a couple bites of a snickers bar and they slowed down but not all the way....can anyone give me an idea of what they think it is
