I’m no stranger to sinus infections. Never had one made me feel this way. I’ve been on Zinc, C and D3 for weeks. I started ivermectin soon as I knew I was exposed. Became symptomatic three days later. My sinuses are basically wide open. This’ll be my fourth dose of Zpack and I’m still experiencing the fever, lethargy and chest discomfort. Don’t appear to be bacterial. The nausea is so odd. It’s not a sick stomach vomit type nausea. It’s an extreme hunger nausea/pain like you get when very hungry, except eating doesn’t make it go away. I’ve not had diarrhea or vomiting.
