The causes of right lower eyelid jumping for several days include physiological causes and pathological causes. Physiological causes are mainly seen in late night, lack of sleep, eye fatigue, mental tension, anxiety, etc. Pathological lower eyelid spasm is often seen in eye diseases and facial muscle spasm in the early stage of eye diseases, eye diseases can include myopia, hyperopia, astigmatism, conjunctivitis, keratitis, etc., the lower eyelid spasm caused by such ocular diseases will not last more than three months, and it is often a paroxysm, and treatment of the ocular diseases can reduce or alleviate the symptoms. It is often paroxysmal and can be reduced or relieved by treatment of the eye condition. If the lower eyelid spasm persists for more than three months, it is very likely to be the early stage of facial muscle spasm, which is caused by the compression of the facial nerve by tumor or misrouted blood vessels, resulting in overexcitation of the facial nerve, and should be done to determine whether the facial muscle has spasm by doing a facial electromyogram and nerve conduction velocity, and need to do a magnetic resonance imaging of the head and tomography angiography to find out the cause of facial muscle spasm.
