Allergies Swollen Lymph Nodes – Enlarged Glands and Allergies

Swollen lymph nodes are a warning to go to the doctor, as they represent a powerful alert system of the body against infections due to viruses or bacterias. Generally, this usually happens when there is an infection in the throat, or ear, although the glands can also become inflamed in the armpit area, or even in the groin area.


But is it possible that allergies are the main reason for swollen lymph nodes? Many people are allergic to different things and may notice a swelling in the neck. Coincidence? Read on to find out.

What are Lymph Nodes?

The ganglia are nodules of various sizes that are found throughout the body. They form a kind of “network” that, taken together, is called the lymphatic system. Its main function is to act as a defense against possible infections.


How to Know if The Nodes are Swollen?

Detecting the inflammation of some nodes is difficult when these are in deep areas of the body, such as the abdomen since it is impossible to touch them.

But many of them are easy to palpate because they are in more superficial places, such as the neck, under the jaw, behind the ears, in the back of the head, in the armpits, in the groin, or on the clavicle. Usually, they turn hard, you can feel some hit in the area, in some cases, you can have a general fever, you feel pain in the area, etc.

Under normal conditions, the nodes remain of a similar size and consistency throughout life. But if they grow, they are called lymphadenopathy and must be studied.


What Can Cause Swollen?

Typically, the lymph nodes become inflamed when there is an infection, whether by fungi, bacteria, viruses, or parasites. This means that the immune system is working properly and that it is fighting to fight it. On the other hand, they can be swollen due to other reasons such as an immunocompromised disease.

The neck and armpits are the most common places where the nodes can be swollen. It will be necessary that you visit your doctor to see exactly what is happening.

Can Lymph Nodes Become Inflamed Due to Allergies?

Yes, since allergies affect the immune system and this causes inflammation of the lymph nodes, usually in the throat/neck area, due to the overwork of the immune system to fight the infection.

This is usually seen in children and adults who suffer from allergies and that cause throat or sinus infections, although seasonal allergies are not usually the main causes of swollen glands since they are not enough for it to happen.


How to Reduce Swollen Lymph Nodes from Allergies?

If you already know that your lymph nodes are swollen as a result of an allergy, to treat it you can do the following:

  • Allergy medication: There are over-the-counter medications to relieve allergy symptoms.
  • Gargle: Gargling with warm water and salt is known to help with throat infections. If the throat improves, the glands in the neck should also improve.

If the swollen persists after a few days, consult with your doctor.


When the reason that causes the enlargement of the lymph nodes is properly treated, they become smaller until they return to the way they were before. However, this de-inflammation does not occur immediately, but gradually reduces and can take weeks to return to normal, even if the cause has been resolved.
