The Reason behind The Ear's Enlarged Lymph Nodes.

Each and every person has a large number of tiny lymph nodes located all over their body. This gland is an essential part of the immune system, along with the lymph vessels. As soon as the lymph nodes start working.
Water will be squandered. Fluid will build up and cause swelling if there is a disturbance. The body's lymph nodes are beneficial organs that support the immune system.
Tissue-derived lymph nodes contain immune cells that can help the body fight off illnesses. The liquid helps to get rid of dangerous substances that could hurt someone. The body contains this part in various places.
Not to mention behind the ears. If there is a disruption, the lymph glands;

1. Contaminated Ears with Bacteria
   One of the reasons why lymph nodes behind the ear become swollen is due to an infection occurring in the ear. This swelling can occur either in front or behind the ear.
   When this occurs, you may also experience a fever and pain in the ear. The presence of fluid accumulation inside the ear can lead to an infection. This condition can be caused by allergies, sinus infection, or the flu.
2. Swelling of the lymph nodes
   Limfadenopati is a condition that occurs in the lymph nodes. The lymph nodes play a role in fighting against infections. When the number of cells that fight infection continues to increase,
   As a result, there will be an accumulation which eventually leads to swelling. In addition to infection, lymphadenopathy can also be caused by inflammation or cancer.
3. Infection on the skin or scalp.
   The infection can spread to the preauricular lymph nodes. This infection can result in disturbances that can lead to fever. In addition to swelling behind the ear,
   The skin around the lymph nodes becomes red and heated, and you might also develop an abscess.
4. Mastoid inflammation.
   More serious conditions may develop if an ear infection is not treated right away. This condition is also referred to as mastoiditis.
   The mastoid, a bony lump behind the ear, may become infected with this infection. This may ultimately result in the development of lumps and pus-filled cysts behind the ear.

It's possible that the lymph nodes' enlargement won't hurt when touched or will only be apparent as a tiny lump.
In order to receive the proper treatment, it is recommended that you undergo additional testing right away with an internal medicine specialist.
