The most important symptom of AIDS is the enlargement of lymph nodes, mainly the superficial lymph nodes including the head and neck, armpits, groin, and for the lymph nodes in front of the ear and behind the ear may also appear enlarged. Some patients may also have systemic manifestations, such as low fever, fatigue, night sweats, and weight loss. Some patients may develop various infections, such as lung infections and central nervous system infections. For the ears, there is no very specific manifestation. If patients have symptoms of the ears, they need to go to the ENT department for examination to rule out any inflammation of these parts, which is not related to AIDS.
