Has anyone else experienced anything like a neurological spasm in their brain or neck?

I have noticed that most of my postconcussion symptoms seem to be pretty familiar to everyone else, but I haven't seen any mention of twitches or spasms. It feels as though there is something building up that tends to get discharged in a kind of spasm. It isn't something that is noticeable to others except that there is visible contraction around the eyes and in the throat. It feels like an electrical discharge or a wave of something.

Please send me a message if you have experienced anything like I am describing. I am curious to know if it is a widespread phenomenon or just me.

Thanks.
