Updated: May 8


A Woman Checking Her Neck for Swollen Lymph Nodes.

Sometimes, people ask, "Can allergies cause swollen lymph nodes?" If you have allergies and the little bumps in your neck (called lymph nodes) feel big or sore, you might want to know why. This article will talk about allergies and how they can affect your lymph nodes, helping you understand more about your health.


What Are Lymph Nodes?

Lymph nodes are small, bean-shaped bumps in your body. They are part of a system called the lymphatic system, which helps keep you healthy. Lymph nodes help filter out bad things like germs and can get bigger when your body is fighting something like an infection or allergies. You can feel them in places like your neck, under your arms, and in your groin. They are like little helpers who work hard to keep your body safe and healthy!


What Are Allergies?

Allergies happen when your body's defense system gets confused and thinks harmless things like pollen, dust, pet hair, bug bites, or certain foods, are dangerous. When people who are allergic come into contact with these things, their bodies release special chemicals called antibodies to try and fight them off. These antibodies can make you sneeze, itch, or swell up when you're near the thing you're allergic to. Allergies can be a pain, but usually, they're not too serious. Some allergies happen only during certain times of the year, like when there are a lot of flowers blooming in the spring. Other allergies can happen all the time, like when someone is allergic to dust or pet hair. Some people are allergic to just one thing, and some people are allergic to many things.


Types of Allergies


1. Respiratory Allergies

Hay Fever (Allergic Rhinitis): Some people are allergic to pollen from flowers and plants. This can make their nose feel stuffy and their breathing tubes get irritated. The lymph nodes in their neck can also swell up because of this allergy.


2. Food Allergies

Some people have strong allergic reactions to certain foods. This might make their whole body react, and once in a while, it could make the lymph nodes swell up too.


3. Insect Sting Allergies

Some people are allergic to bug bites, like from bees or wasps. These allergic reactions can make the area around the bite swell up and get red and painful. In some cases, the lymph nodes near the bite might swell up too.


4. Drug Allergies

Some people are allergic to certain medicines, and this can cause a reaction all over their body. This can cause swelling and other problems, and sometimes, it can make the lymph nodes swell up too.


5. Infections Triggered by Allergies

Allergies can make your body's defense system weak, which can make it easier for you to catch an infection, like a cold or the flu. When you get an infection, your lymph nodes might swell up as your body tries to fight the sickness.


Can Allergies Cause Swollen Lymph Nodes?

Yes, allergies can sometimes cause swollen lymph nodes. When you have an allergic reaction, your body's immune system gets activated, and this can make the lymph nodes in your body swell up. The swollen lymph nodes are a sign that your body is trying to protect you from what it thinks is a danger. Remember, swollen lymph nodes can happen with different types of allergies, like allergies to pollen, food, bug bites, and even some medicines. If your lymph nodes stay swollen for a long time or get really big, it's a good idea to talk to a doctor to make sure everything is okay. Sometimes swollen lymph nodes can mean something else is going on in your body.


Common Allergy Symptoms and How They Affect Your Lymph Nodes


1. Sneezing and Runny Nose

If you have allergies that make you sneeze a lot and have a runny nose, like hay fever, your body's defenses might get more active. This can make the lymph nodes close to your nose and throat a little bit bigger and maybe a little sore.


2. Nasal Congestion

If your nose is stuffy a lot because of allergies, it can cause a bit of swelling and redness around your nose and throat. This might make the lymph nodes in your neck feel a little bigger or tender.


3. Itchy or Watery Eyes

If your eyes itch or water because of allergies, this can make your body's defense system more active around your eyes. This might make the lymph nodes near your eyes and face a little bigger or sore.


4. Skin Reactions (Hives, Eczema)

Some allergies can make your skin have problems like hives or eczema. This can cause swelling and irritation in the lymph nodes near where your skin is having problems.


5. Fatigue and Malaise

Having allergies can make you feel really tired and not well. This doesn't directly make your lymph nodes swell up, but being tired all the time could be a sign that your body's defense system is working harder than normal.


6. Sore Throat

If you have allergies that bother your nose and breathing, they can make your throat sore. When this happens, the lymph nodes in your neck might swell up as your body tries to help fight the allergies.


Remember, if your lymph nodes stay swollen for a long time or get really big, it's best to see a doctor. Sometimes, this could be a sign that something else is going on, like an infection or another health problem. Your doctor can help find out why your lymph nodes are swollen and make sure you get the right care.


How to Treat Swollen Lymph Nodes from Allergies

If your lymph nodes are swollen because of allergies, here are some things you can do to help them feel better:


1. Identify and Avoid Allergens

Try to figure out what things are making your allergies worse, like dust, flowers, pet hair, or certain foods. Then, do your best to stay away from those things or not eat those foods. You might need to change some things in your life, like getting an air purifier for your house or being careful about what you eat.


2. Antihistamines

There are medicines you can buy at the store that can help make your allergy symptoms better and stop your body's defense system from making your lymph nodes swell up. These are called antihistamines. Talk to your doctor or pharmacist to find out which one is best for you.


3. Nasal Corticosteroids

Some nose sprays can help make your nose feel less stuffy and make the inside of your nose less red and swollen. This can help your lymph nodes feel better too, since they're close to your nose. Ask a doctor or nurse if a nose spray might help you.


4. Decongestants

Sometimes, medicines called decongestants can help make your nose feel less stuffy. Using these for a short time can help your lymph nodes feel better too. But, make sure you ask a doctor or nurse before using these medicines for a long time, just to be safe.


5. Warm Compress

To help make swollen lymph nodes feel better, you can put a clean, warm cloth on them for about 10-15 minutes. This can help them feel less sore and swollen.


6. Stay Hydrated

Drinking lots of water can help your body's defense system work well and get rid of bad things in your body. Make sure you drink plenty of water every day to stay healthy.


7. Rest and Relaxation

Make sure you get enough sleep so your body can get better. Getting good sleep and not being too stressed can help you feel better when you have allergies.


8. Consult a Healthcare Professional

If your swollen lymph nodes don't get better or get worse, even after trying things at home, you should talk to a doctor. They can find out what's causing your allergies and give you the best treatment to make you feel better.
