Like I can predict which body part would suddenly move and what direction it’ll move in and move there to minimize how forceful the movement is. I’ve been searching all over for years and I have no idea what causes it. It happens more when I’m cold lol. It doesn’t affect my quality of life or anything it’s just some weird unexplained thing.
Lots of things. Neurological dysfunction, medication side effects, and electrolyte imbalances come to mind immediately. Not a bad idea to get it checked out just in case, if you’re able to.
