I just recovered from covid in January - I had lost my sense of taste and smell first, then I had a dry cough, congestion, fever, and a wicked headache.
I just took acetaminophen for the fever, sudafed for the congestion, and I picked up a steroid inhaler from the pharmacy for when I found it hard to breathe.
For the most part, you just need to sleep it off and replenish your body with electrolytes and some vegetable/chicken stock if you're not hungry. I had no appetite since I couldn't taste so I just drank protein shakes and vegetable stock.
My loss of taste was the worst part, it lasted about three weeks, after which coffee smelled/tasted like onions sauce and a lot of different items tasted off. Now, about two months after originally testing positive, I feel fine.
