Like, as muscle that is either tired, sore, inflamed, etc? Also, do you find that the limb or area you're currently worried about (ie my arm and leg) twitch way more than anywhere else??
My (arm) issues are symmetrical. Twitching is widespread but I notice it's much more present in my legs. When I have twitches in my arms/shoulder/neck, which is a really tensed area to me, I'm not that scared anymore (I used to in the beginning) because it's just benign.
My calfes twitch all the time, but the left one is the one going literally all the time, the right one not that often. I would think it's not that uncommon to have a prefered side.Greetings,LevenLevi
