Sinus Infection in Adults: What Symptoms to Expect

When adults develop a sinus infection, also known as sinusitis, they often experience a range of early symptoms. One of the most common initial signs is facial pain or pressure, particularly around the forehead, cheeks, or the bridge of the nose. Nasal congestion is another typical symptom, making it difficult to breathe through the nose, and it is often accompanied by a thick, discolored nasal discharge, which may be yellow or green.

Many adults notice a reduced sense of smell and taste as the infection develops. Headaches are frequently reported, especially in areas near the affected sinuses. Some individuals may also experience a mild fever, fatigue, or a general feeling of being unwell. Sore throat and cough can arise as mucus drains down the back of the throat, a sensation known as postnasal drip.

These symptoms tend to persist for more than a week and may initially resemble those of a common cold, but they often last longer and can be more severe when related to a sinus infection. If your symptoms are particularly intense, do not improve, or are accompanied by a high fever, it’s important to seek medical evaluation.

Our experienced medical team can quickly assess your symptoms, provide an accurate diagnosis, and recommend the appropriate treatment to get you feeling better as soon as possible. Walk-in appointments are welcome, so don’t hesitate to visit SoCal Urgent Care if you suspect you have a sinus infection or if your symptoms are worsening.

At SoCal Urgent Care, we know it can be difficult to tell whether you’re dealing with a common cold or a sinus infection (sinusitis)—especially since both conditions share symptoms like nasal congestion, runny nose, facial discomfort, and even a cough. Understanding the differences can help you decide when it’s time to seek expert care.

Colds:

A cold is typically caused by a virus and often starts with a sore throat, sneezing, and a clear or slightly cloudy nasal discharge. Cold symptoms usually peak within two to three days and start to improve after that, resolving completely within a week to ten days. While you might feel some mild facial pressure, a common cold rarely causes severe pain or symptoms that last beyond this window.

Sinus Infections:

Sinus infections can develop after a lingering viral illness, allergies, or even bacterial infection. If you notice nasal congestion and facial pain or pressure that lasts more than 10 days without improvement—or if your symptoms seem to get better and then worsen again—you may be dealing with sinusitis. Other signs of a sinus infection include:

• Thick yellow or green nasal discharge
• Significant facial pain or pressure (especially around the eyes, cheeks, or forehead)
• Reduced sense of smell
• Bad breath
• Low-grade fever, fatigue, or tooth pain

In cases of bacterial sinus infection, symptoms are often more intense and longer-lasting.

When to Visit SoCal Urgent Care:

If you’re unsure whether you have a cold or a sinus infection, consider the duration and severity of your symptoms. Most colds resolve on their own, but sinus infections—especially bacterial—may require prompt medical evaluation and possible treatment.

• Symptoms lasting more than 10 days without improvement
• Symptoms that worsen after initial improvement
• High fever, severe headache, or facial swelling
• Vision changes or confusion

Our experienced providers are here to help you feel better quickly. We offer walk-in visits and convenient care for sinus infections, colds, and other urgent health concerns. If you’re feeling unsure, don’t hesitate to stop by SoCal Urgent Care for a thorough evaluation and personalized treatment plan.

Sinus infections (sinusitis) are common and often cause symptoms like nasal congestion, facial pressure, and mild headaches. However, sometimes a sinus infection can become more severe and require immediate medical attention. At SoCal Urgent Care, we want you to know what warning signs to look for so you can get the care you need as soon as possible.

Signs Your Sinus Infection Needs Urgent Care:

• High Fever: If you develop a persistent high fever above 102°F (39°C), it may indicate your infection is worsening or spreading.
• Facial Pain & Swelling: Increasing pain or swelling around your eyes, forehead, or cheeks—especially with redness or trouble opening your eyes—can point to a complication.
• Severe Headache: A headache that doesn’t improve with over-the-counter medication or gets worse over time deserves prompt evaluation.
• Vision Changes: Blurry vision, double vision, or loss of vision are serious symptoms that require immediate medical attention.
• Confusion or Drowsiness: If you’re experiencing confusion, difficulty thinking clearly, or trouble staying awake, your infection could be affecting your brain or nervous system.
• Other Concerning Symptoms: Stiff neck, sensitivity to light, or persistent vomiting should never be ignored.
• Foul-Smelling Nasal Discharge: Green or yellow nasal discharge with a foul odor—especially if you have other severe symptoms—can be an additional warning sign.

If you or a loved one are experiencing any of these symptoms along with a sinus infection, don’t wait. Visit SoCal Urgent Care right away for a thorough evaluation and prompt treatment. Our experienced medical team is here to help you feel better and prevent serious complications.

Sinus infections are a common concern among adults, and the length of symptoms can vary depending on the cause. Typically, acute sinus infections—most often triggered by viruses—resolve on their own within seven to ten days. You might experience nasal congestion, facial pressure, headaches, and thick nasal discharge, which usually improve gradually.

However, if your symptoms last longer than 10 days without improvement, or if they worsen after initially getting better, you could be dealing with a bacterial sinus infection. In these cases, it’s important to seek medical attention. At SoCal Urgent Care, our experienced healthcare professionals can assess your symptoms and determine if you need antibiotics or other treatments to help you recover faster.

Chronic sinus infections, though less common, can persist for 12 weeks or more. If you’re experiencing ongoing or severe sinus issues, visit SoCal Urgent Care for a thorough evaluation. Our team will identify any underlying causes—such as allergies or irritants—and develop a personalized treatment plan to help you breathe easier.
