Twitching Under Left Eye Muscle Spasm Meaning & Complications

Twitching Under Left Eye Muscle Spasm Meaning & Complications

Eye twitching (or myokymia) is an involuntary eyelid muscle contraction, which typically affects your lower eyelid, not your actual eyeball. They usually affect the lower eyelid only but upper eyelid twitching can also occur. Twitching under the left eye is more irritating than harmful.

However, if they happen for weeks or months, they should be diagnosed and treated by an eye doctor. It could signal a serious neurological condition.

The exact reason for twitching under the left eye is still unidentifiable but most people have myokymia because of stress or excess caffeine.


When should I be worried about Eye Twitching?

Frequent eye twitching is often from a condition called benign essential blepharospasm. One of our facial muscles closes the eyelid and another one opens it. Problems with one of them or both can also contribute twitching under the left eye. It could be because of a problem with the basal ganglia (a part of the brain).

  • Parkinson disease
  • Brain damage from inflammation or a stroke. This is especially true for the thalamus, basal ganglia, or brain stem.
  • Reaction to certain mental health medicines
  • Meige syndrome. This is a nervous system movement disorder.
  • Multiple sclerosis
  • Bell palsy

What Causes Eye Twitching?

In general, muscle twitching under the left eye is caused generally by Stress, Alcohol, Caffeine, and Fatigue.

Stress is one of the most common reasons for eye twitching. Get plenty of rest and try to find ways to relax. Yoga or a walk with your pet may help to ease them. Try not to worry about it – a twitch is usually harmless, and worrying can make it worse. Simple stretching and massage the muscles affected by cramps can also help.


Caffeine or certain medications can cause twitching under eyelid. Maybe you are busy or addicted to coffee, the extra caffeine intake could be affecting your nervous system. Try to relax your body naturally by cutting it down slowly. Switch to decaffeinated versions for two weeks and see the results.

Ever experience twitching after having alcohol or liquor, if yes, it’s time to leave it for a while.

And those who use computers, take certain medications (antihistamines or antidepressants, for example), wear contact lenses and consume caffeine and/or alcohol. See your doctor for a dry eye test to decrease the risk of twitching in future. Restoring moisture can also help.


Lack of sleep or too much stress to the eyes from overuse of computers or smartphones is also a common cause for twitching under the left eye. Place it 20-26 inches away from your eyes and a little below eye level. Taking regular breaks after every20 minutes may help. Putting your warm fingers on the eyes for 20 seconds can also help to ease the eye strain. Also, ask your doctor for computer eyeglasses.

However, chronic eyelid spasms may be a symptom of a more serious brain or nervous system disorder.
