Ron, sorry to hear about your sinus issues. I have very chronic sinus issues, but the standard drug treatment given by allergists didn't help me at all. I've found a number of OTC products that do help:
Sambucol dissolvable tablets, which are so good for colds and flu, are also good for sinus
Similasan Allergy Relief nasal spray
Nutribioic grapefruit seed extract (GSE) nasal spray
Silicea 30C homeopathic pellets (or a combination product with Silicea in it)
There are many other products out there. These are just ones I've used successfully.
Vibes you find relief soon!
