A member asked:

My muscles in my legs and arms twitch all of the time. what could cause this?

A doctor has provided 1 answer

A twitch is: A muscle contraction, and it can be caused by electrolyte imbalances, sodium, potassium, calcium, magnesium, or acid-base changes brought on by exercise that builds up lactic acid. Rubbing mobilizes products, increases circulation and re-established homeostasis.
