Hello Otto,
I have the same thing every fall. In my right eye, sometimes when I awaken in the morning, I can hardly open my eye as it has been running and crusted all over my eyes and then burns all day (indoors & out doors). My sinus' react similarly, as they do cause the post nasal drip. Usually around November, they clear up until the next year.
I hope this helps.
This is an ongoing thing these days. I do drink a lot of water, it's the only thing i drink.
During the fall and certain other times of the year, seasonal allergies can cause our eyes to water and our noses to run. I would suggest that your drink more water. Could it be that you aren't hydrated enough to keep your tears a normal consistency? That would be my thought. And it never hurts to drink more water.
