For the past couple of days, my left hand has been twitching, at first, it just started with the thumb occasionally twitching, then when I held onto my thumb to stop it, it went to the rest of my hand, mainly the pointer, and middle finger. My elbow felt weird, like I'd hit my funny bone, but not quiet and when I press down on it, I get a tingle of nerves reacting to it, I've tried this on the other arm, and I couldn't feel any of the nerve's reaction on my right arm. For the past couple of weeks, due to school work, and being vored, I've been on the computer alot, leaning majorly on my left arm, so I'm pretty sure, that that's the cause, only now I don't know what to do about it.Do you know what's going on with my left arm? And if you do how can I get it to stop twitching? I'm having problems sleeping because of the twitching, which I can't afford since school's starting soon. Thank you for reading this any and all advice is welcomed :D
