Sign #7: Swollen Lymph Nodes
The lymph nodes are small glands that are located in the neck. They are an important part of the immune system, and you can almost think of them as outposts that help serve certain parts of the body. They help filter pathogens from the blood, and they also house white blood cells in readiness for when they are needed.
If there is an infection in the body, then the lymph nodes will be expected to get to work dealing with the problem. As they get to work, they can become inflamed as a result of their efforts. This will also cause the neck area to become swollen, and the swelling of the lymph nodes can also often be felt to the touch.
