You need to talk to your doctor.

Your doctor will do tests to determine what you actually have because sinusitis and bronchitis are two different things.

Sinusitis happens when the sinuses (air-filled spaces behind the bones between the eyes and behind the forehead, nose and cheeks) become inflamed or infected, mucus thickens and clogs the openings to one or more sinuses, fluid builds up inside the sinuses causing increased pressure and bacteria can become trapped, multiply and infect the lining.

Bronchitis is an inflammation of the main airways to the lungs called the bronchi. It is primarily caused by viruses and symptoms may last several weeks.

You can take this respiratory illness assessment to help you figure out which one it may be, but you'll still need to see your doctor for the correct diagnosis and course of treatment.

Since viruses may cause either illness, you can't immediately use antibiotics. Antibiotics work to kill bacterial infections. They DO NOT work on infections caused by viruses.

Don't take antibiotics unless they have been prescribed by your doctor for a specific illness. Take the entire course prescribed to you, even if you feel better or if the symptoms have gone away. Once you are done, don't start taking the antibiotics at another time because you might think that you have the same condition.
