It sounds like a lot of mucous. I used to get horrible sinus infections - I worked in a vehicle with an
open door and would breathe car fumes many hours a day. I had to learn to use a Neti Pot to keep my sinuses clear and clean.
When I did get sinusitis I eliminated mucous forming foods and helped my body by eating non mucous forming foods. Radishes were my go to snack food!!!
I googled and I think this site may be helpful. It seems to be what I eliminated and added to combat the mucous. Good luck. I know the misery that sinuses can cause.
