Lymph nodes are small, bean-shaped glands that are a part of the body’s immune system. Distributed throughout the body, they filter lymph fluid, trapping foreign particles like bacteria, viruses, and cellular debris. Their role is to monitor various regions for signs of infection or disease.
Locating Lymph Nodes Near Your Hips
While there are no lymph nodes directly within the hip joint itself, significant clusters are located in the surrounding “hip area,” particularly in the groin and deeper within the pelvis. The most commonly recognized are the inguinal lymph nodes, found in the groin region where the thigh meets the abdomen. These are divided into superficial and deep groups. Superficial inguinal lymph nodes lie closer to the surface, beneath the skin and fatty tissue. Deep inguinal lymph nodes are situated deeper within the thigh.
Further inside the pelvis are the iliac lymph nodes, including external and internal iliac groups. External iliac lymph nodes are found along the external iliac arteries, while internal iliac lymph nodes are located along the internal iliac arteries, deep within the pelvic cavity.
The Function of Lymph Nodes in This Region
The lymph nodes in the groin and pelvic region function in the body’s defense system. They filter lymph fluid draining from specific areas, including the lower extremities, external genitalia, lower abdominal wall, and parts of the pelvic organs.
As lymph fluid passes through these nodes, immune cells actively filter out harmful substances. These nodes initiate immune responses, activating B-cells and T-cells to combat threats. This process helps prevent infections from spreading and aids in responding to diseases.
When Lymph Nodes in the Hip Area Swell
Swelling of lymph nodes in the groin or hip area, known as lymphadenopathy, indicates they are actively fighting an issue. Common reasons for swelling include infections in the areas they drain, such as skin infections or sexually transmitted infections. Inflammation from a lower body injury can also lead to temporary swelling.
Swollen lymph nodes can feel tender or painful and may increase in size. Most swelling is due to common infections and resolves as the body recovers. However, persistent or unusual changes warrant medical attention. Seek medical advice if swelling does not subside within a few weeks, nodes feel hard or fixed, grow rapidly, or are accompanied by fever, night sweats, or weight loss. Persistent swelling can sometimes signal more serious conditions, such as lymphoma or the spread of cancer.
