Sinus infection: If you are seeing a significant amount of bright yellow discharge from your nose, it is one sign of an infection, which may be in your sinuses. These are most commonly triggered by viral infection, but allergies can also cause sinus congestion. Most sinus infections get better on their own, but if you have sharp pain or tenderness in the face, or fever, it can require treatment with antibiotics.
