Sinus Infections

What Causes a Sinus Infection?

Sinus infections happen when your sinuses become inflamed and congested — and unfortunately, a lot of everyday culprits can set it off. Common causes include:

• The common cold
• The flu (influenza)
• Seasonal allergies
• Bacterial infections (including Streptococcus, Haemophilus, and Moraxella)

Whether it's a virus, bacteria, fungi, or allergens doing the dirty work, the result tends to feel about the same: miserable.

Sinus Infection Symptoms

Not sure if what you're feeling is a sinus infection? Here are the most common signs to watch for:

• Postnasal drip — that fun sensation of mucus dripping down the back of your throat
• Runny nose with thick yellow or green mucus
• Nasal congestion (stuffy nose)
• Facial pressure or pain, especially around your nose, eyes, and forehead — and it may feel worse when you move your head or bend forward
• Tooth pain or pressure
• Ear pressure or pain
• Fever
• Bad breath or an unpleasant taste in your mouth
• Cough
• Headache
• Fatigue

If several of these symptoms are hitting at once, there's a good chance a sinus infection is to blame.

Sinus Infection Treatment Options

The good news? Most sinus infections are very treatable — and many can be managed at home. For mild or early symptoms, try:

• Decongestants
• Over-the-counter (OTC) cold and allergy medications
• Nasal saline rinses
• Staying well-hydrated (drink up!)
