Is it normal to feel lymph nodes in your neck?

A large number of lymphatic tissues are distributed in the neck of a normal human body. The structure is usually small in size and usually less than 0.5 cm in diameter, so it is difficult to touch it at ordinary times. Occasionally, as long as it is not accompanied by pain, it is a normal phenomenon. If its size is too large, and obvious pain occurs after touching, it indicates that there are diseases such as infection or inflammation in the body.
