Sounds like a form of Intention Tremor to me. You intend to make a small movement, and then there is an almighty twitch, and the hand ends up somewhere else, I cannot put a forkfull of food in my mouth with my left hand. ear, yes, up nose, yes. In mouth? No way. The only thing that seems to minimise it is to conciously move the hand very slowly - any fast movement will result in a twitch. So far, it is only my left hand that is affected - good job I am right handed. Geoff
I haven’t had any problems recently. In the past I’ve had things literally jump out of my hands. Luckily it’s never been anything breakable, usually a book or my Kindle, or a remote control. It always startled me when it happened because there hadn’t been any conscious movement to cause it.
