Hi Jim,
I have the same sinus problems after almost 2,5-3 years. No difference whatsoever. Tried neti pot for a while, but had to stop since it caused overload and a burning nose - energies gathering at the top of the nose inside, sort of... guess the spot we try to reach with kechari, the water massaged the spot and I got into overload. Too much energies in the area, and more sensitive nostrils leading to nose bleeding. (Yes, experimented to have the right salt level, but nothing worked out ok, so had to stop.)
