Did you tip your head sideways when you used the Neti pot ?
I did, and it made a bad situation so much worse
The Neil Med system has worked wonders for me post surgery/during high pollen days. It uses a saline solution that you mix yourself, and you can make it as strong or weak as you like.
Only use distilled water for the mix
Tap water just has too much crap in it that even after you boiled it will irritate your sinus cavities nooks and crannies
JohnnyJ’s advice of doing it in the shower is spot on
I usually place the mixed solution in a plastic bowl of hot water to warm the solution / keep it warm as I take a
HOT shower, and do the rinse near the end. The hot moist air as you shower will help loosen all the schmoo so it rinses out better
... try it ...
It may just be the ticket for your chronic / recurring problems
