There's a hard pimple on the left side of the chin

This may be a lymph node, which is a unique organ of mammals (waterfowl also have two pairs of lymph nodes). In normal people, the superficial lymph nodes are very small, mostly less than 0.5cm in diameter, with smooth and soft surface, no adhesion to surrounding tissues, and no tenderness. When bacteria enter the body from the injured area, lymphocytes will produce lymphokines and antibodies to effectively kill bacteria.

The result is reactive proliferation of lymphocytes and histiocytes in the lymph nodes, which makes the lymph nodes enlarged, which is called reactive proliferation of lymph nodes. There are also viruses, some chemicals, metabolized toxic products, denatured tissue components and foreign bodies that can cause reactive hyperplasia of lymph nodes. Therefore, the enlarged lymph node is the beacon of the human body and an alarm device.

Lymph nodes often gather in groups, and there are also shallow and deep groups. Most of them are distributed along the blood vessels and are located in the active part of the body. In the limbs, lymph nodes are mostly located in the flexor side of the joint; in the body cavity, they are mostly arranged along the vascular trunk or near the organ hilum. The lymph nodes of chest, abdomen and pelvis are mostly located around the visceral hilum and large blood vessels.
