Seasonal Allergies: Causes and Triggers

When allergies strike, the body’s immune system goes into overdrive– mistakenly identifying harmless substances such as pollen or pet dander as threats. This triggers a range of reactions, including the release of histamines, which cause typical allergy symptoms. The most common allergens include pollen, mold spores, dust mites, and pet dander. It’s important to be able to identify the signs and symptoms of seasonal allergies in order to manage them effectively.

The most common seasonal allergy symptoms include:

  • Sneezing
  • Runny or Stuffy Nose
  • Itchy, Watery Eyes
  • Coughing
  • Fatigue
  • Headache
  • Sore Throat

The Connection Between Allergies and Swollen Lymph Nodes

Lymph nodes are small structures located throughout the body, primarily in the neck, armpits, and groin. They play a crucial role in the immune system, filtering out harmful substances and producing immune cells to help fight infections. When allergies occur, the immune system’s response can lead to inflammation of the lymph nodes. When allergens enter the body, they can cause inflammation in the lymph nodes as the immune system works to eliminate them. This can cause the lymph nodes to swell and become tender to the touch.

It’s important to note that not all cases of swollen lymph nodes are due to allergies. Infections, such as the common cold or flu, can also cause lymph node swelling. However, if you have a history of allergies and notice swelling after exposure to known allergy triggers, it could be possible that allergies are the culprit. 

When To Seek Medical Attention 

In most cases, swollen lymph nodes due to allergies are harmless and will resolve on their own once the allergic reaction subsides. However, if you’re concerned or if the swelling persists for more than a week or two, it’s a good idea to consult a healthcare professional. Your provider can help determine the underlying cause of your swollen lymph nodes and recommend appropriate treatment if necessary. This can include allergy testing to identify specific triggers and lifestyle changes to reduce your exposure. In some cases, medication may be prescribed to alleviate symptoms and reduce inflammation.
