Facial muscle spasm, also known as facial muscle twitching. It is a condition of involuntary twitching of the half side of the face. The twitching is paroxysmal and irregular, with varying degrees, and can be aggravated by fatigue, stress and voluntary movements. The onset of the twitching usually starts from the orbicularis oculi muscle and then involves the whole face. The disease occurs mostly after middle age and is commonly seen in women. The cause of this disease is unknown, and modern Western medicine lacks a specific treatment for it. At present, symptomatic treatment is generally used, but the effect is not ideal. Symptoms: Facial muscle spasm is a twitching of one side of the face (individuals appear bilateral spasms), and the more nervous and excited the spasm is, the more serious it is. As the initial symptom of facial muscle spasm is eyelid jumping, folk have “left eye jumping for money, right eye jumping for disaster”, so generally will not cause.
