Spring Allergies or Sinus Infection? How to Tell the Difference and When to Visit Urgent Care

Spring brings warmer temperatures and better weather for outdoor activities. Shopping at your local plant nursery like Stanley’s Greenhouse to update your flowers beds or visiting the Knoxville Botanical Garden for inspiration is one enjoyable way to spend a warm spring afternoon. Unfortunately for those living in the South, we know all too well about spring pollen season as the trees and flowers begin to bloom out. Congestion, sinus pressure, and a runny nose can make it hard to tell whether you’re dealing with seasonal allergies or a sinus infection. While the symptoms may overlap, the causes and treatments are different. Knowing the differences can help you decide when at-home care is enough and when it’s time to visit urgent care. 

If you’ve been struggling with seasonal allergies, visit AFC Urgent Care Chapman Highway today for fast relief. 

What Are Seasonal Allergies? 

Allergies occur when your immune system overreacts to a normally harmless substance called an allergen. Common triggers include pollen, dust mites, pet dander, mold, certain foods, and insect stings. 

During spring allergy season, exposure to pollen from trees, grasses, and weeds can trigger symptoms that last for weeks or even months. 

Common Seasonal Allergy Symptoms 

• Sneezing 
• Runny or stuffy nose (typically clear drainage) 
• Itchy, watery eyes 
• Skin rash or hives 
• Wheezing or coughing 
• Nausea (in some cases) 
• Mild fatigue 

Allergies typically: 

• Do not cause fever 
• Include itching (eyes, nose, throat, skin) 
• Improve with antihistamines or allergy medications 
• Flare up during certain seasons 

What Is a Sinus Infection? 

A sinus infection, also called sinusitis, occurs when fluid becomes trapped in the sinuses; those air-filled spaces located behind the eyes and along the nose, allowing bacteria or viruses to grow. Sinus infections commonly develop after a cold, respiratory illness, or untreated seasonal allergies, when inflammation prevents proper sinus drainage. 

There are two main types of sinus infections: acute and chronic. Acute sinusitis typically lasts less than four weeks and often follows a recent respiratory illness. It may occur once or twice per year and usually resolves with appropriate treatment. Chronic sinusitis, on the other hand, lasts 12 weeks or longer and may involve multiple infections throughout the year. Because chronic sinusitis can significantly impact daily life, medical evaluation is important to determine the most effective treatment plan. 

Symptoms of a Sinus Infection 

Sinus infections can range from mild to severe. Symptoms often include: 

• Facial pressure or pain 
• Headache 
• Thick yellow or green nasal discharge 
• Postnasal drip 
• Fatigue 
• Loss of smell or taste 
• Jaw or tooth pain 
• Sore throat 
• Ear pain 
• Fever (sometimes) 

Unlike seasonal allergies, sinus infections commonly cause facial pain and may include fever or thick nasal discharge. 

Seasonal Allergies vs. Sinus Infection: The Key Differences 

Understanding a few key symptom differences can help you determine whether you’re dealing with seasonal allergies or a sinus infection: 

Nasal discharge: 

• Allergies typically cause clear, watery drainage 
• Sinus infections often cause thick yellow or green mucus 

Itching: 

• Common with seasonal allergies (eyes, nose, throat, skin) 
• Rare with a sinus infection 

Fever: 

• Allergies do not cause fever 
• Sinus infections may include a low-grade or persistent fever 

Facial pain or pressure: 

• Mild sinus pressure can occur with allergies 
• Sinus infections often cause more intense facial pain, heaviness, or tenderness 

Duration of symptoms: 

• Allergies can last for weeks or months during allergy season 
• Sinus infection symptoms often last more than 10 days or worsen after initial improvement 

If your symptoms persist, worsen, or include significant facial pain or fever, it may be time to visit AFC urgent care for evaluation. With no appointment needed and clinics open 7 days a week, you can get fast answers and relief when you need it most. For your convenience, book here today.
