The groin beats are probably the femoral artery, not the lymph nodes. The heart pumps blood throughout the body and is constantly contracting and diastolic, so arteries with shallow ends can be palpated. These include the radial artery, carotid artery, superficial temporal artery, dorsalis pedis artery, etc. The femoral artery can also be felt in the groin. Groin beats can also occur if there is trauma to the femoral artery in the groin, resulting in a hematoma or aneurysm. Lymph nodes belong to the immune system and collect tissue fluid. Although there are indeed lymph nodes in the groin, they are usually not accessible and do not pulsate, and it is recommended to consult a doctor promptly if an enlarged lymph node is detected. Therefore, if you find that the groin is throbbing, you should consult a doctor in time to get a clear diagnosis and then follow the doctor’s instructions for treatment.
