Step 4: Read and complete the decision guide to learn more about your symptoms.
Coughs and Colds
These symptoms most commonly result from a viral or bacterial infection or allergy. If you have symptoms that specifically suggest a bacterial infection ("acute sinusitis"), then it is important for you to see your doctor for an evaluation so that you can receive appropriate treatment.
Symptoms that would suggest a bacterial sinus infection include:
pus (murky or opaque fluid that is yellow, green, or brown) in the nose instead of clear mucus
a toothache in your upper set of teeth
tenderness of your face around the sinus areas (brow, nose, and cheeks)
a lump (that could be an enlarged lymph node) in your neck or near your ear.
Do you have one or more of the symptoms from this list?
