This is how I fought it. I took large amounts of vitamin c, elderberry, cut large peices of garlic put them in my sinuses to kill any infection, drank hot liquids – hot soups, teas, hot lemon water, used sinus flush daily, washed and sanitized my hands frequently, drank fire cider vinegar w/o sugar, took quercetin and vitamin c, drank tonic water with quinine, drank oil of oregano, sprayed my room and areas with rosemary oil, tea tree oil and anise, cleaned my handles phone or any surface I was touching. Avoided all unclean foods. These are the things I did in the natural.
The most important thing I did was pray🙏 And read my bible.
