As it seems to be the case, every new thing that happens convinces me that some terrible disease is "progressing." I certaintly am not new to the twitching. But for the past couple of weeks my forearm will twitch whenever I right click the mouse at my computer. Basically when I quickly move my middle finger up and down my forearm will twitch near my elbow (I know these are the muscles that mover your fingers). Clean EMG early Jan, twithcing since the end of Nov. Should this be worrisome? Has anyone else experienced this?
