Allergies can cause various symptoms, including swollen lymph nodes. While allergies and swollen lymph nodes can sometimes be alarming, they typically aren’t serious and treatment is available. Of course, if you have an allergic reaction that causes you to have breathing issues or serious swelling, you should always seek emergency medical attention immediately.
With that in mind, let’s take a bit of a deeper dive into the link between allergies and swollen lymph nodes. In this blog, we’ll discuss the causes of allergies, symptoms and treatments that may help with both your allergies and swollen lymph nodes. Read on to learn more.
Seasonal, or environmental, allergy symptoms can vary from person to person, but there are quite a few common symptoms that you can expect to experience if you have allergies. These symptoms may include the following:
Remember, not everyone experiences the same symptoms from allergies, and these symptoms can range in severity. Still, it’s good to understand the different symptoms you may experience and learn your potential triggers so you can avoid your allergens and mitigate your symptoms.
There are quite a few triggers for allergies. Some of the most common allergens include:
When you come into contact with your allergy triggers, your immune system mistakes them as a threat and triggers an immune response, releasing chemicals like histamine to fight the perceived threat. The symptoms you experience are this immune response and your body trying to get rid of the allergen.
Lymph nodes are small lumps of tissue that are part of your body’s immune system function. They are found throughout the body and are used to filter lymph fluid, which is essentially waste created by your body’s tissues. Lymph nodes are essential for keeping your body healthy.
Sometimes, lymph nodes may get swollen and inflamed. As part of your body’s immune system, this swelling and inflammation can occur when your body is trying to fight off an infection or other perceived threat. In the case of allergies, your immune system is mistaking these allergens as a threat, which can lead to the lymph nodes swelling.
Your lymph node’s immune response is actively attempting to eliminate the allergens from your body. When your lymph nodes are swelling, it’s typically to fight a bacterial or viral infection, so it’s a sign that your immune system is functioning as it should. You should notice that your lymph nodes return to normal as your allergy symptoms subside. However, you should make sure to speak to your doctor if the lymph node swelling happens suddenly, if the swelling is painful or if it doesn’t subside on its own.
Allergens are anything that can trigger an allergic reaction in an individual, and lymph node swelling can often occur as part of your body’s immune response to an allergen. This means that technically any allergen can cause your lymph nodes to swell. The aforementioned allergens like pollen, pet dander, dust mites, mold and certain foods can be likely culprits if you’re experiencing allergy symptoms.
Your body may react differently to allergens than other individuals. So, an allergen that causes lymph node swelling for you may not do the same to another person with the same allergy.
Whether you’re dealing with allergies, swollen lymph nodes or both, it’s important to know when to seek medical attention. While both conditions are typically not serious, there are times when medical intervention may become necessary.
For allergies, you should seek emergency medical attention if your symptoms are persistent and severe. Symptoms like difficulty breathing, severe swelling and intense pain are all signs to seek medical help right away.
Swollen lymph nodes will typically subside on their own, but you should seek medical attention if the swelling is persistent. You should also seek medical attention if the swelling is abnormally large, if the lymph nodes are painful, if there is drainage from the lymph nodes or if you’re experiencing other symptoms such as difficulty breathing alongside swelling.
For allergies and swollen lymph nodes, various diagnostic tests and treatment options may be recommended.
To diagnose allergies, your Allergy Specialist will typically conduct a physical examination and go over your medical history before ordering an allergy test. An allergy test, such as a skin prick test or blood test, is used to identify the specific allergens that cause your symptoms.
For allergy treatment, your health care provider will likely recommend that you reduce your exposure to your allergen as much as possible. This may also require some lifestyle changes, like vacuuming more often to remove allergens, using a HEPA filter, avoiding outdoor time during peak pollen hours and more. There are also over-the-counter allergy medications to help with symptom relief. For long-term relief, allergy shots or allergy drops are sometimes an option.
For swollen lymph nodes, your doctor won’t typically conduct additional tests unless there is cause for medical concern. To diagnose potential lymph node issues, tests like blood work, imaging scans or biopsies may be needed to rule out any underlying conditions.
For swollen lymph node treatment, you can usually just allow the swelling to subside on its own. However, if the swelling is persistent and painful, your health care provider may need to determine the root cause for the swelling and treat that condition and refer you to an allergy specialist when appropriate.
Your health care provider may also suggest some natural remedies to help with your allergy symptoms. Here are some natural remedies they may suggest:
It's important to remember that natural remedies may not work for everyone, so it's best to consult with a healthcare professional before starting any new treatment.
