Its been driving me bananas since last night. Its a very visible and very frequent twitch and went on through the night and still going.
I'm convinced that its an overuse thing after battling with a screwdriver and a recalcitrant screw for over an hour yesterday. My hand aches, my arm muscles ache and even the muscles in my back around the arm ache.
Is there anything I can do to stop it please, I keep thinking there must be some massage point or something that would sort it out.
