I have had a red eye for 3 days with a feeling of "itching" as if I constantly have an eyelash in my eye and it hurts. It is not watering. What should I do?

If you have had a red eye for three days with a feeling of irritation, as if there is constantly something in your eye, and it is painful, it is recommended to irrigate your eye with artificial tears while waiting to determine the cause of these symptoms. Avoid rubbing your eye and possibly keep it closed until your appointment to prevent further irritation. Visiting an optometrist is the best course of action in this situation.
