There are several reasons why the muscles under the eyes of patients are throbbing: 1. If the patient appears by chance, consider that it is caused by physiological factors. For example, patients with mental tension, staying up late, poor sleep, stress, anxiety, and fire can lead to involuntary jumping of the muscles under the eyes. 2, organic diseases can also easily lead to jumping of the muscles under the eyes, such as demyelination of the central nervous system when infected with a virus. 3, if there are tumors in the brain, especially tumors in the pontocerebellar horn region, compression of the facial nerve can also easily lead to patients with jumping of the muscles under the eyes. 4. Facial muscle spasm disease. If the muscle throbbing under the eye lasts for a long time and progresses and worsens, the patient must consult a hospital in time to improve MRI and electromyography to clarify the cause.
