two days ago my elbow started twitching intermitently. no pain.
then, last night, as i was reaching for something, my elbow kind of locked. it hurt. Since then, it has hurt off and on, on the upper part of the arm right next to the elbow. (right next to the pointy bone). No other part of my arm hurts.
this is my left arm (I am right handed) and i have never injurted the arm and don't remember bumping it recently. It sort of cramps, or catches, with pain when I move it. I can't see this as a stress related injury since i don't use my left arm for strenuous acticities (writing, throwing, etc). I haven't played sports within a week, either.
Any suggestions?
