follow up....

I believe that the answers indicating just plain dry sinus tissue may be the culprit. I woke up this morning sneezing and the inside of my nose feeling raw. I went to the drug store on my way to spin class and the pharmacist recommended a product that is a saline based gel with aloe that is sprayed into the nose. I think that this may be the ticket.

Thanks for the ideas. I'll keep you up to date on whether this works.
