4. Swollen Lymph Nodes.
Your body is made up of a vast amount of tubes called arteries and veins. These vessels carry blood away from the heart and back to the heart, and they feed every cell of the body. Similarly, there is a third vessel in your body called lymph vessels and lymph nodes, which play a role in carrying toxins and waste from the body. When you have an infection, your lymph nodes may appear swollen, which is evident through palpation of the area. If you notice that your neck area just under your jaw is a little swollen or tender to the touch, you may have swollen lymph nodes. Consider having your doctor give you an assessment to determine if your lymph nodes are swollen and consider discussing all symptoms you may be having as well.
