Easy. Go get tested for Covid.
You’ll invariably test positive for Covid (whether you have it or not), so now you have Covid.
Eat some soup and get some rest.
I know some people that get tested (or do a home test) obsessively whenever they feel under the weather. Kind of creepy.
We were overwhelmed with ragweed this fall and allergy symptoms so bad that I thought mine had become a sinus infection. Fortunately it did not. Those I noted above would not consider air quality as a factor when we pointed it out.
It.had.to.be.covid. They worship covid in some perverted way.
