Do you have a source for corona infecting the inferior part of your throat rather than the inferior part? I know you spoke to doctors, but I find it incredibly difficult to find credible sources other than either
incredibly simplified accessible articles on mainstream health websites, stating that a symptom is "throat pain"
or having to go through 20 pages of medical research which I understand basically nothing of.
The main difference was it took the superior part of the throat instead of the inferior. Talking with doctors they tell me I had all the symptoms.
The problem with it is that at first it is "benign"(I had high fever for "just" two days) if your body stops it before getting into the lungs. Once it gets there it could be nasty(as it produces cytokine storm syndrome there) very fast.
So it is very easy to get confident.
Even the flu could get very dangerous is you get it combined with something else like a bacteria at the same time.
