I have had lower eyelid twitching for 3 months.

Eyelids are eyelids. If they twitch occasionally, it is not a serious problem. The lower eyelid has been twitching for 3 months, which is obviously abnormal. It is more likely caused by disease. The most likely cause is facial spasm. We need to have a comprehensive understanding of the facial spasm and figure out the situation so that we can better treat it. Next, let’s look at hemifacial spasm.

Primary hemifacial spasm usually occurs after middle age and is more common in women. In the early stage of the disease, the orbicularis oculi muscle on one side has paroxysmal involuntary twitching, which gradually and slowly spreads to other facial muscles on one side of the face. The twitching of the muscles at the angle of the mouth is the most noticeable. In severe cases, it may even affect the platysma muscle on the same side, but the frontalis muscle is less affected. The severity of the convulsions varies, and they are paroxysmal, rapid, and irregular. The convulsions are mild at first, lasting only a few seconds, and then gradually lengthen to several minutes or longer, while the intervals between convulsions gradually shorten and the convulsions become more frequent and severe. In severe cases, the disease becomes rigid, causing the eye on the same side to be unable to open, the corner of the mouth to be crooked to the same side, and the person to be unable to speak. The disease is often aggravated by fatigue, mental tension, and voluntary movements, but the person cannot imitate or control the attack by himself.

A convulsion can last from a few seconds to more than ten minutes, with intervals of varying lengths. The patient feels upset and unable to work or study, which seriously affects his physical and mental health. Most convulsions stop after falling asleep. Bilateral facial muscle spasm is very rare. If there is, the disease usually occurs on both sides one after the other. After one side stops convulsing, the other side will start to convulse. Moreover, the convulsion on one side is lighter than that on the other side. There have been no reports of bilateral convulsions occurring at the same time. A small number of patients experience mild facial pain during convulsions, and some cases may be accompanied by ipsilateral headache and tinnitus.
