Seasonal allergies are known for causing sneezing, itchy eyes, and runny noses– but what about swollen lymph nodes? If you’ve noticed tenderness or swelling under your jaw or in your neck during allergy season, you may be wondering if the two are connected. While swollen lymph nodes are not one of the common symptoms of allergies, they can occur in some cases. In this blog, we’ll explore what you need to know about how seasonal allergies affect your immune system, when lymph node swelling might be related, and when to see a doctor.

What Are Lymph Nodes & Why Do They Swell?
Lymph nodes are small, bean-shaped glands located throughout the body. They are a key part of your immune system, helping to filter out harmful substances like bacteria, viruses, and allergens. When your body detects an invader or inflammation, the lymph nodes near the affected area can swell as they work to fight it off.
Swollen lymph nodes often indicate that your immune system is responding to something. The most common causes include:
- Strep Throat
- Mono
- Common Colds
- Sinus infections
- Inflammatory conditions
- Allergic reactions
Can Allergies Cause Swollen Lymph Nodes
Yes, but indirectly. Seasonal allergies themselves typically do not cause swollen lymph nodes. However, they can lead to conditions that trigger lymph node swelling, such as:
- Sinus Congestion or Infection: When nasal allergies cause significant inflammation and mucus buildup, this can lead to a secondary sinus infection. The resulting infection may cause lymph nodes in the neck or under the jaw to swell.
- Chronic Postnasal Drip: Ongoing irritation from mucus draining down the throat may cause throat inflammation or even minor infections, prompting the nearby lymph nodes to respond.
- Increased Immune Activity: In rare cases, a strong immune reaction to allergens might cause temporary, mild lymph node swelling, especially if the body is responding to multiple triggers at the same time.
Allergies vs. Infections: Identifying the Cause of Your Swollen Lymph Nodes
To figure out what’s causing your swollen lymph nodes, consider your other symptoms:
More Likely Allergies:
- Itchy or watery eyes
- Sneezing and nasal congestion
- Clear, runny mucus
- No fever or body aches
- Symptoms last for weeks or follow a seasonal pattern
More Likely Infection:
- Fever or chills
- Sore throat with pain when swallowing
- Yellow or green mucus
- Fatigue or body aches
- Sudden onset and worsening over time
If you’re unsure whether allergies or an infection is the cause, seek a professional diagnosis. A medical provider can perform a physical exam, evaluate your symptoms, and order tests (like a rapid strep test or imaging) if needed to rule out infection or other causes.
