Sinus infections, also called sinusitis, are inflammations of the sinuses, air-filled spaces behind your forehead, cheekbones, and nose. They occur when these spaces become blocked and filled with fluid, creating a breeding ground for bacteria, viruses, or fungi.
Common Symptoms
Recognizing a sinus infection relies on identifying several key symptoms. These often develop gradually, but sometimes appear suddenly.
- Facial pain or pressure: This is often described as a dull ache or pressure in the forehead, cheeks, or between the eyes. Congestion: A stuffy nose is a hallmark symptom, making it difficult to breathe through your nose. Thick, discolored nasal discharge: The mucus may be yellow, green, or even brownish. Postnasal drip: Mucus dripping down the back of your throat can cause a sore throat and cough. Reduced sense of smell or taste: Inflammation can affect your olfactory nerves. Fever: A fever is common, especially with bacterial infections. Headache: Sinus headaches can be severe and often worsen when bending over. Fatigue: Feeling unusually tired is also a frequent symptom.
Types of Sinus Infections
Sinus infections are classified by their duration:
Acute sinusitis: Symptoms last less than four weeks. Subacute sinusitis: Symptoms persist for four to twelve weeks. Chronic sinusitis: Symptoms continue for twelve weeks or longer.
