I'm on day 5 after testing positive for covid and apart from 1 day of feeling very tired and hot I've been fine. However everytime I wake up from sleep I feel like I can smell things burning. I have young children so it causes me a lot of panic thinking that they have got into the kitchen and started a fire. I know this probably isn't a very concerning symptom but I was just wondering if anybody else has had this and how long it took to pass?
