My covid experience started with a sore throat and a fever for 3-4 days. I then went two days with no symptoms before developing a cough. 48 hours later I was in the hospital with 84% O2 saturation, on 60L of oxygen, and had a pretty servere case of pneumonia. Please keep an eye on your o2 levels and if they start dipping to the low 90s, get to the hospital asap.
If you want to read about my adventure that included 7 days in the hospital the first time, then 7 days at home, then another 5 days in the hospital, go read the last 5 or so pages of the "I just tested positive" thread. I am a pretty healthy (a little extra weight but no other comorbidities) 38 year old male. I was not afraid of covid at all, and should have been. My wife, parents, in laws, kids, and sister in law all got it at the same time and I was the only one hit hard with it. But i came very close to not making it apparently (more than one doctor told me to buy lottery tickets as I was getting better).
Please do not blow it off as if it's nothing. It very well may be nothing especially if you got the infusion, but please watch your o2 levels. It affects everyone differently, and even the doctors were telling me they still have no idea how it works or why it does what it does to your body.
