Why do my muscles twitch?

[Naveed Yaseen]

Muscle twitches, especially involving the eyelids, calf or thumb — are fairly common. Rarely, they can be a sign of a nervous system disorder, the US National Library of Medicine says. Signals of a serious muscle problem include a change in muscle sensation, size, and a feeling of muscle weakness. On the other hand, most muscle twitches aren’t anything to worry about and only last for a few days or less. The NLM offers this list of common causes:

* Having a dietary deficiency.

* Getting too much caffeine.

* Taking certain medications, such as steroids, estrogen hormones or diuretics.

* Exercising.

* Having anxiety or stress.
