I agree with Lucy. He needs to be seen by an MD asap. No one on this site has any idea of his medical history, drugs he is on, etc. This is a question to be answered by his MD.
Good luck.

I'd say take him to the dr. you might get more help from a different forum, hun. this one is about addiction problems. i can sure see why it scares you. it would scare me too.
