What is the cause of the lump in the thigh and pubic groove?

Lumps in the thigh and pubic groove may be related to swollen lymph nodes and should be treated with anti-inflammatory drugs.

Lymph nodes are distributed throughout the body and are important immune organs of the human body. They can be divided into superficial lymph nodes and deep lymph nodes according to their location. Normal lymph nodes are mostly between 0.2 and 0.5 cm in size and are often distributed in groups. Each group of lymph nodes collects lymph from the corresponding drainage area. For example, the lymph nodes behind the ear and in the mastoid area collect lymph from the scalp; the submandibular lymph node group collects lymph from the floor of the mouth, buccal mucosa, gums, etc.; the cervical lymph nodes collect lymph from the nose, pharynx, larynx, trachea, thyroid, etc.; the supraclavicular lymph node group collects lymph from the esophagus, stomach and other organs on the left, and collects lymph from the trachea, pleura, lungs, etc. on the right; the axillary lymph node group collects lymph from the upper trunk, breast, chest wall, etc.; the inguinal lymph node group collects lymph from the lower limbs and perineum. Understanding the relationship between the two is of great clinical significance for determining the location and nature of the primary lesion.
