@Tropical_Willie My dad says the same, and two of my girlfriends. I know it’s a real thing. My dad the last time he was dismissing his drip, congestion, and cough I told my mom to stay away from him. They both said it was his typical sinus mess. She caught it, they finally tested, and it was covid. I believe you are more susceptible to getting sick because of your pre-existing condition, but its still catching viruses and bacterial infections going around.
One of my friends similar story, then she gave it to her husband, not covid this time. Actually a lot of people on the cruise ship caught it, hers became severe and she wound up needing oxygen at home, antibiotics. Her husband was not very sick and better in a week.
I knew about 7 people last month, not covid, needing antibiotics for their sinus infection. A bacterial sinus infection was going around. Maybe not the case in your situation this time, but I just see it again and again that it’s actually contagious.
The allergen did not disappear in two weeks, but now you aren’t getting sick from it? Outdoor allergens from bloom usually last for 4–8 weeks.
