Depending on the cause of your sinus pressure, the way you treat your symptoms will look differently. If you experience sinus pressure, it’s most likely caused by sinusitis. Sinusitis means your sinuses are inflamed. Often, sinusitis is caused by a bacterial infection, but it can also be caused by a cold, nasal problems, or even allergies.1 Your paranasal sinuses are the hollow air spaces within the bones of your face surrounding your nose.2 Mucus leaving the frontal sinus, behind your forehead, and your maxillary sinuses, behind your cheeks, drain through the ethmoid sinuses behind the bridge of your nose.2 If your nose is swollen, your sinuses can be blocked, causing pressure and pain.1 When the sinuses in your nose become blocked, your other sinuses are likely to also become clogged, which is why you feel sinus pressure in different parts of your face.2 Other symptoms that may accompany your sinus pressure include fatigue, cough, congestion, and postnasal drip.1 If your symptoms are severe and last for more than a week, you should talk to your healthcare provider. Based on your symptoms and looking at your nose, they will have a better idea of what is causing your sinus pressure. If you have bacterial sinusitis, you may be prescribed an antibiotic.2
