Another time when they can be felt is when you have an infection, (for example, a sore throat or an ear infection which can make the neck lymph nodes enlarged, painful and tender as these are the nearest lymph nodes to the site of infection). If you’re dealing with an illness and have swollen lymph nodes, they should return to normal size as you recover. Since the lymph nodes work to help the dogs immune system, it is common to see systemic symptoms. It occurs in systemic pathologies, such as infectious diseases and sepsis. Generalized: when lymph nodes throughout the body are affected. However, sometimes they can be felt in slim people as smooth pea-sized lumps, usually in the groin. Lymph nodes are small glands forming clusters in different body areas, such as the neck and underarms. We most commonly notice them on the lymph nodes of the neck.

Lymph nodes can only be felt in certain areas of the body (see Figure 1): Swollen lymph nodes in the neck can manifest as tender or firm lumps, usually ranging from the size of a pea to a cherry. The lymph nodes filter out harmful organisms and abnormal cells before the lymph reaches the blood stream. They’re an important part of the immune system and are found throughout the body. These help to fight bacteria, viruses and anything else that causes infection. They are found at intervals along the lymphatic vessels like ‘beads on a string’. The lymph glands (or lymph nodes) are small lumps of tissue that contain white blood cells. Lymph nodes (‘glands’) are small ‘bean-shaped’ nodules that contain millions of infection fighting lymphocyte cells. It drains into lymphatic vessels then larger lymphatic vessels called ducts in the neck before joining the blood stream near the heart (see Figure 1). Lymph fluid bathes the cells of the skin and internal organs.
