Here is a 'for instance'...
You are laying down, watching a movie, or sitting down watching a movie. You are completely still and then your foot moves on its own...or your elbow jerks a little. I know this is not a spasm, or a fasciculation..but rather a myoclonic jerk. What freaks me out is the short...short list of possible explanations of it whilst awake, and all are HORRIBLE..including mad cow disease. When looking at physiological reasons, it mentions anxiety, but then defines it as "tremors, shakes, or spasms". Spasms are painful contractions of muscles, tremors and shakes are self explanatory. I can't find anything saying anxiety or stress causes body jerks or flinches while awake.
Is there anyone here that personally experiences these in any degree while awake? So I can at least convince myself that yes, anxiety CAN cause body jerks..
