2. Swollen Lymph Nodes
Lymph nodes run through the body and have their own circulatory system. This system is sort of like the blood system, except it carries lymphatic fluid instead of blood. Problems with lymph nodes are a classic sign of infection. As your body tries to compensate and fight off the bacteria, these nodes can swell up fairly large and may even become tender to the touch or large enough to be visibly noticeable.
The most common area for swollen nodes is in the neck area, but nodes can extend far up, almost to the facial region. Other nodes are located in the armpits and in the groin region. It’s not uncommon for these to be vulnerable to swelling as well.
This swelling doesn’t happen immediately after you are infected. It most commonly happens 7 to 21 days after you first were exposed to the bacteria strain.
