When coughing with swollen eyes, consider whether the cough is due to a series of symptoms caused by a viral infection. When the virus invades the respiratory tract, producing symptoms such as cough and runny nose, it may also infect the conjunctiva, producing conjunctivitis and therefore swollen eyes. At this time, you can actively treat the cold, drink warm water and do not eat spicy and stimulating food, and the swollen eyes will disappear when the cold and cough get better. Consider whether there is a problem with liver and kidney function. In this case, you can go to the hospital for routine blood tests to see how the blood picture is, or you can check the chest CT or liver and kidney ultrasound to clarify the cause.
