I now think my muscle spasms and twitching was because of some nutritional imbalance, possibly a low calcium level or B12 deficiency. The spasms have gone away though my hands occasionally twitch involuntarily. I am taking vitamin supplements. If you have bloodwork done, it should show deficiencies if they are responsible for your spasms. I hope you get some relief. When my spasms first appeared it scared me as I feared Parkinson's or ALS. I found out that it is most often some benign condition.
