Unfortunately, it does sound like a drug induced or blount trauma induced episode. That is not to say that it is. Nor is it to say that if it is, that it isdue to some illegal activity on his part. For example, he could have had a seisure of some sort which might have caused a fall that he is not aware of. Or he could have had an allergic reaction to something. Or he could have an epileptic episode. There is also the possibility of some rare bite or disease such as Stiff Man Syndrome ( http://www.med.yale.edu/neurol/progr...stiff_man.html ).

It looks like you are doing all you know to do. Make him as comfortable as possible. If it were me, I would probably take something like liquid Benadryl in the mean time. It is not me, however, and I am not recommending anything here. Although Benadryl seems relatively safe, there is no telling what contraindications it could have with a street drug if that should happen to be a part of the problem.

Please keep us posted.
