What is Myokymia?
Myokymia is characterized by a spontaneous involuntary contraction of muscles. It may be described by many people as a quivering of muscles or a trembling of the skin. The twitching can be so fine as to not be observed by someone looking at the person.
Myokymia of Other Locations on the Body
Myokymia may occur on other locations in the body and this is called neuromyotonia. Facial Myokymia is characterized by twitching or quivering of muscles on one side of the face. Facial Myokymia can be caused by multiple sclerosis (MS), cerebrovascular accident (CVA), tumor in the brainstem, or after an episode of Guillain-Barre syndrome. Facial Myokymia should be evaluated to determine its etiology. Myokymia can affect the oblique eye muscles and cause double vision.
Twitching of Eyelids
It usually starts suddenly and will resolve in two or three weeks. The twitching occurs more often on the lower eyelid compared to the upper eyelid. The muscles involved are called the orbicularis which you use to close your eyes. This is different from the spams related to blepharospasm that involve the face or eyelids.
Causes of Eyelid Twitching
Typical causes for twitching of the eyelid is stress, anxiety, tiredness, fatigue, caffeine, lack of sleep, drugs, alcohol, during holidays, over work, and other causes from a change from normal life patterns.
Treatment of Myokymia or Twitching Eyelids
Conservative treatment for eyelids twitching is recommended as this is usually temporary. Warm compresses applied to the eyelids for ten minutes three or four times a day may help by relaxing muscles. You may try over-the-counter anti-histamine to reduce any swelling. Getting more rest and better night’s sleep may improve the twitching. Reduce time on computers and lower the lighting in the room may also help. You should reduce or eliminate caffeine. Obviously, if there is something in your life causing stress you should try to reduce the stress. Very small doses of Botox can be used for treatment in chronic cases.
Twitching of eyelids is a common problem that is almost always temporary and needs only conservative treatment unless it fails to resolve after three or four weeks.
