The presence of lymph nodes in the neck is usually normal. There are many lymph nodes in and around the human neck, which are usually difficult to be touched, but may become enlarged due to infection and other factors and be touched. Lymph nodes are mostly oval or bean-shaped and vary in shape and size. When a local tissue or organ in the body is diseased, the invading foreign body can spread to the corresponding lymph nodes through the lymphatic vessels, and these lymph nodes have the function of blocking and clearing the foreign body, and are the body’s barrier against the spread of virus. If the lymph nodes in the neck are not infected, it is usually difficult to touch them by hand. When they can be easily touched, it indicates that the body is being attacked by inflammation, tuberculosis, etc. It is necessary to promptly consult a hospital for imaging examination to find the cause of the disease for treatment. It is recommended to take a light diet, avoid spicy and stimulating food, actively participate in physical exercise, pay attention to rest, avoid overexertion, and if lymph nodes are persistently palpated in the neck, promptly consult a hospital for examination.
