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.
If you are in a position to see a neurologist, that could be a great way to get a better answer. I have seen a neurologist regularly for almost 30 years for something else, but also have minor tremors/twitches that predated why I see the neurologist. My twitches are like an eyebrow vibing, or a small portion of thigh muscle, etc. Anyway, neither of the neurologists I saw for over ten years felt I should be concerned, but I also didn’t pursue it. I had other concerns. A main/family doctor may be able to help, also. Not sure.
Anyway, doctors should listen, and then they may have questions about things like family history. That is really where the quality of life can matter. It isn’t about now, but later. If you can afford the doctor visit.
