Sinus infections, also called sinusitis, are a common reason people in Anaheim feel stuffed up, run down, and sore across the face. Most are caused by viruses and clear up on their own, but some linger or turn into a bacterial infection that needs care. Knowing the difference helps you treat it sensibly and recognize when to be seen.
What a Sinus Infection Is
The sinuses are air-filled spaces behind the nose, cheeks, and forehead. Sinusitis happens when the lining of these spaces becomes swollen and normal drainage gets blocked, so mucus builds up and germs can grow. It is often triggered by a cold or by allergies. Sinus infections are usually described by how long they last: acute sinusitis lasts up to about four weeks, while chronic sinusitis lingers for several weeks or keeps coming back.
Common Symptoms
- Nasal congestion and a stuffy or runny nose
- Facial pain, pressure, or tenderness around the eyes, cheeks, or forehead
- Thick, discolored nasal discharge or postnasal drip
- A reduced sense of smell and taste
- Headache, and pain that worsens when bending forward
- Cough, sore throat, bad breath, and tiredness
- Sometimes a low fever
A common cold and a sinus infection share many symptoms. Sinusitis is more likely when symptoms last longer than about ten days, or when they improve and then get worse again.
What Causes Sinus Infections
- Viral infections such as the common cold, which are the most frequent cause
- Allergies that cause ongoing nasal swelling
- Bacteria, which can take hold after a cold blocks the sinuses
- Nasal structural issues such as a deviated septum or nasal polyps
- Irritants like smoke and air pollution
What You Can Do at Home
Most sinus infections, especially viral ones, improve with supportive care:
- Rest and drink plenty of fluids to help thin the mucus
- Use a saline nasal spray or rinse to clear the nasal passages
- Try a warm compress over the face and breathe in steam for comfort
- Use a humidifier
- Over-the-counter pain and congestion remedies can help, following the label
Antibiotics do not help a viral sinus infection. They are only useful when a bacterial infection is the cause, which a provider can help determine.
Who Is More Prone to Sinus Infections
Some people get sinus infections more often than others. The risk is higher for people with allergies or asthma, frequent colds, exposure to smoke, or structural issues such as a deviated septum or nasal polyps. If you are getting sinus infections again and again, it is worth looking into why, since treating an underlying cause such as allergies can reduce how often they happen.
Red Flags: When to Seek Care
See a provider if symptoms last more than about ten days without improving, get worse after starting to improve, include a high fever, or come with severe facial pain or swelling. People with frequent or recurring sinus infections should also be evaluated. Seek emergency care for swelling or redness around the eyes, vision changes, a severe headache, confusion, or a stiff neck, which can signal a serious complication.
