It could be restless legs syndrome. My legs twitched too and it freaked me out. Turned out to be a symptom of anxiety. Do you have weakness or fatigue in legs.

For bubbling or twitching of the calves get your B12, Calcium and Potassium levels checked. B12 deficiency causes neuromuscular problems.

You must take B12 as a shot or sublingual (under the tongue),
