Dan Moore, certified physician assistant at McLaren-Greater Lansing Internal Medicine, a partner of McLaren-Greater Lansing, is treating upper respiratory infections, including sinus infections.

Symptoms include think, yellow, foul-smelling nasal discharge; pain or pressure around the face, eyes and mouth; headache, nasal obstruction and congestion. You may or may not have a fever or cough.

The symptoms of a sinus infection can be similar to a cold. If sinus pain and thick yellow or green mucus last longer than a week, you should see a doctor to determine if you have a sinus infection.

A sinus infection is diagnosed after a physical exam. A doctor will usually prescribe antibiotics.

Decongestants and other drugs help decrease swelling in your sinuses and nasal passages.

Steam and hot showers may help, too.
