11.Phantom Smell: Sinus Infection
Sinus infections can also make things taste unpleasant or bland. The phantom smell usually goes away on its own in a few weeks or months. Your doctor might suggest that you rinse your sinuses with a saltwater solution.
12.Yellow Snot: Infection? Maybe
You can’t really tell exactly what’s going on just by the color of your snot. Colored mucus may be a sign of a virus or a bacterial infection, but it might also be due to an allergy, among other things. Your immune system uses white blood cells to get rid of bacteria. This turns your snot yellow as it fights the germs. After 10 or more days it might start to turn green. That’s when you may want to talk to your doctor about antibiotics. It should become clear after you get better.
