Try using a Neti pot. They are available at most drug stores. Takes a couple time to figure it out, just make sure you keep your head down, tuck chin into neck, turn head slightly.This should stop the salt water from going into throat.(harmless but tastes salty) If it doesn't just reposition head until you find the correct position. The saline really cleans out the sinus. Will make you feel so much better. The Neti pot is really good for allergies as well. I use it daily and now I rarely get sneezing and runny eyes. Also drink water+++.
