Devastating. Extreme fatigue. As sick as you really want to be for a couple of weeks. You say recently, but don't say how recently. Given we are in the covid pandemic, that would be more likely. I discovered when I was in college when I got very sick for a couple weeks that tonsilitis and mono have the same symptoms. But I was, as I say, pretty sick. I was young and got over it. But you know, you can't diagnose yourself and neither can we. It could be anything or nothing at all. But a sore throat is a symptom of covid.
