Causes of Muscle Twitch, Muscle Twitching, Muscle Twitches
Muscle twitches are minor involuntary muscle contractions. The twitching may be visible under your skin and is rarely a major health concern. However, a muscle twitch can be a sign of a nervous or muscular system issue.
Twitching that is not caused by a disease or health condition are known as benign twitches. This type of twitch is very common and often comes and goes.
Benign twitches often occur in your eyelids, calf or thumb. And some universal twitching triggers are stress, anxiety, fatigue, caffeine and exercise.
Some of the health conditions that can be a cause for a muscle to twitch or muscle twitches are:
- neuralgia
- myopathy
- poisoning
- myoclonus

Muscle twitching may worsen due to dehydration and electrolyte imbalances. If you suspect that this is your dietary situation, try gulping down an electrolyte drink to promote a healthy balance.
