Sometimes when I am thinking of doing something and change my mind a bunch of times my hand will jerk like I've sent too many messages and it's short circuiting. Like on a computer program at work going to click here but deciding no I want to click over here and going back and forth on my decision and all the decisions are being sent to my hand and it can't deal with the overload. My best way of describing it anyways.
Gabapentin stopped it for me and also gave me pain relief.Proof that everyone is different! That one I would check with your doctor. One of your med's may be giving you that feeling or a pinched nerve in you shoulders or neck - too much screen time and I think we are all at fault for that one. Good Luck Jennay, Hugs xxx
