March/April this year - I had a congested nose and so did the person # 1 who was living with me - except I complained about it and they weren't bothered by it. Went to get tested, started off with a false negative but the pcr a few days later was positive. Then I realized my sense of smell and taste were slowly fading away. Person #1 was fine within a day but for me fatigue, high fever, headache, and a bunch of other stuff followed for weeks on end. I took vitamins, tried to exercise and eat. Didn't help me much if I'm being honest. Ended up losing 20 pounds in the first week.
After all of that, I kind of became obsessed with good smells lol.
Wish you the best in your recovery.
