Lyme Disease Symptoms; 11 Early Signs & Symptoms of Lyme Disease

Enlarged lymph nodes

Enlarged lymph nodes

As it happens with many other infectious diseases, Lyme disease may include enlarged lymph nodes as one of the most common signs. These lymph nodes might be dispersed throughout the body, or they might be regional lymph nodes near skin lesions and other external manifestations of the disease.

The reason why lymph nodes start to swell in the event of an infectious disease such as Lyme disease is that these structures are an important part of the immune system. They are filled with lymphocytes, ready to be replicated. When there’s colonization by bacteria, lymphocytes take a sample of this bacteria, travel through the lymph vessels into the lymph nodes, and deliver this information to the newly replicating lymphocytes. The lymph nodes become active, creating more and more lymphocytes to fight the invasion. That is why they become larger.

Enlarged nodes are useful for the diagnosis in association with other signs and symptoms that we will further mention in this article. In all cases, your doctor will be qualified to know the difference between a simple viral infection that does not require any treatment and Lyme disease, which needs to be treated as soon as possible.
