3. Swollen Lymph Nodes
The lymph nodes can become swollen if there is an infection in the body. The swelling usually occurs in or near the area where the infection is present. The lymph nodes filter fluid that moves through the body. When there is an infection present, they respond by swelling. Swollen lymph nodes can be sore and tender. In some cases, they can swell a lot and become very noticeable.
In other cases, they are not easy to see, but simply feel like tender spots in the body. Lymph nodes are often the most noticeable in the groin, under the arms, around the jawline, and above the collarbone. In most cases, the swelling goes down on its own once the infection leaves the body. Doctors may want to monitor the swelling closely to make sure there are no other underlying causes. If they become too painful, pain medication can help reduce the swelling and discomfort.
