When spring arrives, many people are ready to spend more time outdoors. Warmer days in Littleton make it the perfect season for gardening, yard work, fishing with new equipment from Ascent Fly Fishing, or simply enjoying a quiet afternoon on the porch.
But spring also brings something less pleasant, pollen season. As trees, grasses, and wildflowers begin to bloom, pollen levels rise and many people start experiencing symptoms like sneezing, congestion, and sinus pressure.
One challenge during this time of year is that seasonal allergies and sinus infections can feel very similar. Because both affect the sinuses, it can be difficult to tell which one is causing your symptoms. Knowing a few key differences can help you decide how to treat your symptoms and when it might be time to visit urgent care.
Why Spring Triggers Allergies
Seasonal allergies occur when your immune system reacts to substances in the environment called allergens, During the spring months, pollen from trees, grasses, and plants is one of the most common triggers.
Common allergens include:
- Tree pollen – Juniper, Oak, Maple, Birch, Ash, and Elm (peak April to early June)
- Grass pollen – Kentucky Bluegrass, Timothy, and Ryegrass (May to August)
- Weed pollen – Ragweed, Russian Thistle, Sagebrush, Pigweed, and Lamb’s Quarters (peak from late summer to early fall)
People with spring allergies often experience sneezing, a runny or stuffy nose, itchy or watery eyes, and a scratchy throat. Some may also notice mild coughing, fatigue, or skin irritation. Unlike infections, allergies do not cause fever, and symptoms often improve with antihistamines or other allergy medications.

What Causes a Sinus Infection?
A sinus infection, also known as sinusitis, develops when the sinus cavities become inflamed and blocked. The sinuses are hollow spaces located behind the forehead, cheeks, and nose. When mucus becomes trapped in these areas, bacteria or viruses can grow and cause infection.
Sinus infections often develop after:
- A cold or respiratory illness
- Severe nasal congestion
- Untreated allergies
- Ongoing sinus inflammation
Symptoms of a sinus infection may include facial pressure, headaches, thick yellow or green nasal mucus, fatigue, and postnasal drip. Some people also experience tooth pain, ear pressure, or a reduced sense of smell. In some cases, a low-grade fever may also occur.
How to Tell the Difference
Although allergies and sinus infections share symptoms like congestion and sinus pressure, a few differences can help you tell them apart.
Allergies usually cause clear, watery nasal drainage and noticeable itching in the eyes, nose, or throat. Symptoms may come and go depending on pollen levels and typically do not include fever.
Sinus infections, on the other hand, often produce thicker yellow or green mucus along with facial pain or pressure. Symptoms also tend to last longer, often more than 10 days, and may worsen instead of gradually improving.

Tips to Prevent Allergy Symptoms and Sinus Infections
While pollen can’t be avoided completely during spring, a few simple habits can help reduce exposure and keep symptoms under control.
Wash Your Hands After Being Outside
Pollen easily collects on your hands after outdoor activities. Washing your hands regularly helps prevent allergens from spreading to your eyes, nose, or mouth.
Blow Your Nose After Outdoor Activities
Blowing your nose after being outside can help remove pollen from the nasal passages before it triggers inflammation or congestion.
Shower and Change Clothes
Pollen sticks to hair, skin, and clothing. Taking a shower and changing clothes after yard work or outdoor chores can prevent pollen from spreading around your home.
Stay Hydrated
Drinking plenty of water helps thin mucus and supports healthy sinus drainage.
Limit Outdoor Time on High-Pollen Days
Checking local pollen counts can help you plan outdoor activities when levels are lower.
These small steps can help reduce irritation and lower the chances of allergy symptoms turning into a sinus infection.
When to Visit Urgent Care
Many mild allergy symptoms can be treated at home, but certain symptoms should be evaluated by a medical provider. Severe facial pain, persistent fever, or symptoms that lasts longer than 10 days may indicate a sinus infection that requires treatment.
You should also seek care if you experience trouble breathing, frequent sinus infections, or congestion that makes itdifficult to sleep. AFC urgent care providers can quickly determine whether your symptoms are caused by seasonal allergies, sinusitis, or another respiratory condition.
