Unfortunately, allergies often share symptoms with the common cold and flu, making it hard to know what’s actually causing you to feel unwell.

If you’re not feeling your best and aren’t sure what’s behind your symptoms, here’s how to tell the difference—and when to seek care.

What are Your Symptoms?

How long symptoms last

• Colds: Usually last 7–10 days, with mild symptoms sometimes lingering another week.
• Allergies: Can last for weeks or even months as long as you’re exposed to the allergen.

 If symptoms last longer than 10 days or aren’t improving, it’s time to see a provider.

Body aches and fatigue

• Colds: Muscle aches and fatigue are common.
• Allergies: Do not typically cause body aches.

Fever

• Colds: A low-grade fever may occur.
• Allergies: Never cause a fever.

If you have a fever along with congestion or cough, allergies are unlikely.

Nasal drainage

• Allergies: Thin, clear, watery mucus.
• Colds & infections: Thicker mucus that may appear yellow or green.

Note: Yellow or green mucus does not automatically mean a bacterial infection or that antibiotics are needed. If symptoms are worsening or not resolving, a provider can help determine next steps.

Eye symptoms

• Allergies: Itchy, watery, red, or puffy eyes are very common.
• Colds: Eye symptoms are uncommon.

If eye irritation is one of your main complaints, allergies are more likely.

What Are Seasonal Allergies?

Seasonal allergies occur when your immune system reacts to substances that appear at certain times of year, such as pollen from trees, grasses, and weeds. This reaction—known as allergic rhinitis or “hay fever”—causes inflammation in the nose and sinuses, leading to congestion, sneezing, and itchy eyes.

While substances like dust mites, pet dander, and mold are often grouped with allergies, they are typically present year-round. Seasonal allergies, on the other hand, flare up when specific pollens are in the air.

Common Symptoms of Seasonal Allergies

Symptoms can range from mild to disruptive and may include:

• Runny or stuffy nose
• Sneezing
• Itchy, watery eyes
• Nasal congestion
• Sinus pressure
• Full or plugged sensation in the ears

In rare cases, hives or rashes may occur. If this happens, medical attention should be sought promptly.

Treating and Managing Seasonal Allergies

There is no cure for allergies, but symptoms can be managed effectively. Helpful strategies include:

• Limiting exposure to allergens when pollen counts are high
• Staying indoors on dry, windy days
• Removing clothing worn outside and showering after heavy exposure
• Drying laundry indoors instead of outside
• Using HEPA air filters at home
• Taking over-the-counter antihistamines, decongestants, or nasal sprays
• Performing gentle saline sinus rinses
• Talking with a provider about prescription options if symptoms persist

Pediatric Considerations

Children can experience seasonal allergies just like adults. In fact, about 80% of children with asthma also have allergies, which can trigger asthma symptoms. While allergies can’t be cured, they can be safely treated.

Depending on your child’s age and symptoms, treatment may include:

• Antihistamines or nasal sprays
• Saline rinses
• Avoidance of known triggers

Children with severe allergies may require an epinephrine auto-injector. Always consult your provider before starting any new medications.

Is It a Cold or Allergies?

Colds typically begin with a sore throat and develop into cough and congestion, resolving within 3–14 days. Allergies tend to cause prolonged sneezing, congestion, and itchy eyes that can last for weeks or months.

If you’re unsure what’s causing your symptoms, or if you’ve been sick for more than a week, it’s best to seek medical evaluation.
