If there is a situation where the left eyelid keeps jumping, it is actually more likely to be facial muscle spasm, which may occur in the face. In another case, it may also be a precursor of the onset of cardiovascular diseases, cerebral infarction, stroke, myocardial infarction, etc. Once the left eyelid jumping occurs, you need to go to the nearest hospital for examination, including electrocardiogram, cardiac ultrasound and cardiovascular angiography. Through these tests, we can actively look for the primary cause of the left eyelid jumping, and actively treat the primary cause, and do a good job of cardiovascular prevention and health care.
