I could see that being a reason.

I do agree that you should not be sticking the PCR tests anywhere near your body. Ethylene oxide and everything. Besides that it does not accurately test for anything. Besides that covid does not exist except on a computer screen. Not trying to insult you or anything but taking their test is playing right into their hands.

If you genuinely are sick, take care of yourself the old school way. Drink plenty of fluids. It will help your lungs expel any phlegm. If you have a fever, starve yourself. If you can stand it. There is a point between hunger and starvation where your immune system kicks into overdrive. And if you're interested, I make smoothies that help me get over any tiny colds. I put spinach, carrots, broccoli, and mixed Frozen vegetables. Well everything is frozen. Then I add turmeric, cinnamon, and vanilla extract for flavoring. The real kind. It helps tremendously. I am a heavy smoker and it is always clearing out my lungs for me. I never take any medicine and I am around children constantly because I have a daycare at home. They are always sick and so are their parents who are all injected. I have stayed relatively very healthy over the last 2 years.

Wishing you all the best & a speedy recovery!
