Syphilis | Stages, Symptoms, Treatment & Prevention

2- Inflammation of the lymph nodes in the area of the sore

As you may know, the lymph nodes are small glands in charge of filtering a clear circulating fluid through the lymphatic system: the lymph. These glands become inflamed in response to infections and tumors. Enlarged lymph nodes are usually located near the area of the sore, usually the groin.

The lymph circulates the body through ducts similar to blood vessels in an alternate circulation called lymphatic system. These small glands store white blood cells, and undergo replication when there’s an infection. That is when lymph nodes start to swell.
