It’s weird how it affects everyone differently. I didn’t have a whole lot of congestion. My ears plugged up and my left ear was nearly completely deaf for a month but I never had any significant congestion in my airways. The headache was the worst part but that only lasted about 6 hours for me. The fever took a few days to break and the random fatigue lasted a few weeks.Not really. so congested I've become a mouth breather. I think I drank a gallon of water through the night.
