Covid management. It take to go away?

I'm on day 5 of covid19. I'm having throat burn when inhaling. Feeling like my nasal airway is wide open and the air is causing throat burn... it is quite prominent when I'm inhaling deeply. Having occasional breathing problem. Increases when i am working ( have to, since all family members are infected and I'm a mother of 4yr old child) and at night. So much so, that I need elevated pillow to sleep..also have trouble sleeping.However, SPO2 is always ranging in 97-98%. Lost complete smell. We are managing at home, husband is on day 10 and is doing well. Child had fever for 2 days, then rash in his back... now no symptoms, he is on day 7. Are these symptoms anything to worry? How long does it take to go away? What should I be looking out for, to identify emergencies...
