Hey, when I had my MS Health Anxiety scare I pretty much had hypnic jerks and would just burst out of sleep and then they just went away after realizing I was wrong. Now with my Health Anxierty about ALS I am obsessed with my mouth and tongue, despite being told I'm fine. So at night I'll go to bed fine but when I wake up in the middle of the night I get extreme anxiety and I'll literally shake..legs everywhere. Where it bothers me the most though is my jaw. If my teeth are together they chatter and I was so obsessed with maybe my tongue moving I'd jam it against the roof or back of teeth...of course being a muscle it does shake some...anyways, anyone else get the shakes in a concentrated area?
