Old family remedies:
onion and garlic (fresh) simmered in clear broth. I prefer beef, but chicken is also fine. The preparation of the onions and garlic will help clear the sinus, the steam helps, and the soup is soothing. Avoid dairy products.
Mix a hot toddy simple variation: fresh lemon juice, hot water, and a "shot" of whatever distilled liquor you have (rum or bourbon) sweetened with honey. Or hot orange juice with gin or vodka and a dash of cinnamon. (This is not recreational and should be limited to one, maybe two, AND use caution if using any medication.)
Drink the toddy while in the bath or before the shower.
Take the hot shower or bath. If you wash your hair, avoid getting water in your ears, eyes, and nose, unless you are deliberately using the spray to "wash your sinuses".
Bundle yourself in warm blankets or slumber bags.
Replace your tooth brush or disinfect it and change your pillow case daily. If you have a better time of day, try going outside for some fresh air or ventilating your apartment or house.
Call your mom. If she can't come to you, at least you will have an opportunity to talk and ask her advice, and plan for when you feel better.
If Chinese delivery is available, try the hot sour soup or other clear soups.
Best wishes,
