2 years ago something started happening... I can't control my right foot, my right hand, and my mouth sometimes. If I try to resist my body from controlling it, I usually get a muscle pulled. Anyways, first my knee bends so my right foot goes inward, then my hand curls up, then my mouth opens wide and I usually have to cover it up. So I look like a crippled old man.

This has been going on for 2 years and I don't know how it happened. Should I go to a doctor? Will I get this disease I have treated? If anyone knows what it is, could you please tell me?
