I got into a cough / sinus circle, clear up one & the other started. The only thing that's worked is clear up the cough then do a nasal wash once a day, look up netti pot ! It's a bit wyrd doing it to start with but once you get used to it, it's ok. Do follow the instructions, lean forward & do not use straight tap water. I was lucky & Aldi had some for sale & the salt at the same time.
