Interesting. I have been wondering about my sinuses. Every morning when I wake up I cough up mucus for about 15 minutes and have to blow my nose about 20 times. After that my nose is clear for the rest of the day, but the mucus in my throat stays. I had been drinking all my liquids warm, but stopped when the weather got so hot. I am going to try going back to warm liquids too see if that will help my throat. Thank you for your response and giving me something to think about.
