9. Swollen Lymph Nodes
The human body is armed with a network of small, interconnected structures whose purpose is to hold B and T lymphocytes and help the body fight off infection. These structures, called lymph nodes, are found throughout the body, but they are mainly located in the neck, armpits, and groin.
If microorganisms such as bacteria or viruses enter the bloodstream, the lymph nodes become inflamed. In the case of HIV infections, close to 70% of patients who have tested positive for the virus report moderate to severe inflammation of the lymph nodes.
