Last year my doctor believes I may have had COVID, but I was outside the window to be tested by the time I got treatment. My O2 dropped to 90%, got a fever (about 101), body aches, and felt run down. My body temperature suddenly crashed to 91-92F and had the worst chills I ever had but was able to recover from that with supplemental heat before spiking another fever. The worst of the symptoms lasted maybe 3-4 days before I was left with a sore throat that lasted maybe 3 weeks, and I also had to go on antibiotics for pink eye. Ever since then, I've had long-term issues with my stomach getting a random "pinching pain" that I never had before, and it can last for days at a time. Doctors have done so much imaging and tests to find out what is going on, but everything keeps coming up normal. Even had a colonoscopy lol
