Left eyelid jumping is a kind of eyelid tremor, which occurs when the orbicularis oculi muscle is repeatedly contracted after being stimulated. It is possible that the left eyelid jumping is related to tobacco and alcohol stimulation, excessive fatigue, tension, diseases of the eye itself, improper eye use, local nerve damage, and facial neuritis. If there is excessive eye use and eye fatigue, it may lead to local nerve tension, spasm and jumping. You can do hot compress and massage, which is good for relief, reduce the time of using the eye and reduce the stimulation of bright light. If there is conjunctivitis and keratitis, you can use drugs such as levofloxacin eye drops and tobramycin eye drops, together with B vitamins. If there is hemiplegia and limited movement on one side of the face, antiviral drugs such as ribavirin and hormonal drugs such as dexamethasone are used, together with acupuncture, massage and moxibustion at acupuncture points for treatment.
