I've had a twitch in my middle finger for a few weeks now and it's getting really annoying. I've got a very slight tingling down my forearm too. It's doesn't hurt in the slightest, just feels strange. I think it could be a repetitive strain injury or something. I haven't climbed much for a few months and just trying to go a bit more often now. The twitch doesn't seem to affect the strenght of the finger too much
Has anyone had this before? If so what was it and how do you get rid of it?
