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.
I’ve dealt with it my whole life
You could try seeing a neurologist to get an EMG/NCS done. It ranges between uncomfortable to moderately painful, but it doesn’t take too long. My experience is that it never gives you an answer, but apparently some people do get results.
