Yes some people do get watery eyes when they have the flu.
When you have the flu and have a fever your eyes can begin watering and that is normal.
You might also experiencing a burning eye sensation feeling along with the watery eyes when you're experiencing the flu.
It's all normal and nothing to worry about and when your fever goes away then watery eyes should too as long as the watery eyes are not caused by allergies.
I almost always get watery eyes when I have the flu and when I have a fever and after the fever goes away the eyes stop being watery.
You'll also usually experience body aches, muscle aches, fatigue, weakness, chills etc with the flu.
Most cases of the flu are not serious and just have to basically run their course for a week to 14 days.
You can take cold and flu medicine to help ease the symptoms of the flu.
But mostly rest and staying hydrated is about all you can really do to get rid of the flu.
If your flu gets worse or doesn't go away within 14 days or you have a fever of 100 F or more and it doesn't go down normally then go to urgent care or the emergency room just to be safe.
Sometimes the flu can be deadly so be careful although most cases of the flu are not deadly.
