Understanding your body is crucial for staying healthy, and knowing where your lymph nodes are located is a key part of this. Lymph nodes are small, but vital components of your immune system. If you’ve been advised to check your lymph nodes, or you’re simply interested in learning more about your anatomy, understanding the location of groin lymph nodes in women is important. This article will guide you through the lymphatic system, pinpoint the location of groin lymph nodes, also known as inguinal lymph nodes, in women, and explain how to perform a self-examination.
Understanding the Lymphatic System
Imagine a network within your body that works alongside your blood vessels. This is your lymphatic system. It’s made up of lymphatic vessels and lymph nodes, and it plays a critical role in your body’s defense against infection and disease. Lymph, a clear fluid, circulates through this system, collecting waste products, bacteria, and viruses from your body’s tissues.
Think of lymphatic vessels as tiny streams that merge into larger rivers. These vessels collect lymph and carry it towards lymph nodes, which are like filtering stations along these lymphatic pathways.
Locating Groin Lymph Nodes in Women (Inguinal Lymph Nodes)
Lymph nodes are concentrated in several areas throughout your body, including your neck, armpits, and groin. The lymph nodes located in your groin are called inguinal lymph nodes. These are particularly important as they drain lymph from the lower part of your body, including your legs, pelvic area, and external genitalia.
In women, groin lymph nodes are situated in the inguinal region, which is the area where your thigh meets your abdomen. You can find them in two main groups:
Horizontal Chain
This group of inguinal lymph nodes runs horizontally just below the inguinal ligament. The inguinal ligament is a band of tissue that extends from the anterior superior iliac spine (the bony prominence at the front of your hip bone) to the pubic tubercle. To locate this chain, feel along the crease where your thigh meets your lower abdomen.
Vertical Chain
The vertical chain of inguinal lymph nodes is located along the upper part of your thigh, following the line of the femoral vessels. This chain extends downwards from the horizontal group. To find these, move your fingers down from the horizontal chain, along the inner aspect of your upper thigh.

These inguinal lymph nodes are essential for filtering lymph from the lower extremities and pelvic region, playing a vital role in immune surveillance and response in these areas of the female body.
Why are Groin Lymph Nodes Important?
Groin lymph nodes serve as a critical part of the immune system in women. They filter lymph fluid from:
- Legs and Feet: Draining lymph from the entire lower limbs.
- Pelvic Area: Filtering lymph from the external genitalia, perineum, and lower abdominal wall.
- Lower Back and Buttocks: Collecting lymph from these regions.
When you have an infection or inflammation in these areas, the inguinal lymph nodes may become enlarged as they work to fight off the infection. They can also be affected by certain cancers that may spread through the lymphatic system.
How to Perform a Groin Lymph Node Self-Exam
Regular self-examination of your groin lymph nodes can help you become familiar with their normal feel and detect any changes early on. Here’s how to check your groin lymph nodes effectively:
-
Lie down comfortably: Lying down helps to relax the muscles in your groin area, making it easier to feel the lymph nodes.
-
Locate the Horizontal Chain: Place the pads of your fingers (index and middle fingers) of one hand just below the crease where your thigh meets your lower abdomen.
-
Use Gentle Circular Motions: Press gently but firmly in a circular motion, feeling for any lumps or bumps. Compare both sides for any differences.
-
Locate the Vertical Chain: Move your fingers down along the inner part of your upper thigh, below the horizontal chain. Again, use gentle circular motions to feel for any lymph nodes.
-
Check Both Groins: Repeat the process on the other groin area to compare.

Normally, you might not be able to feel your groin lymph nodes unless they are enlarged. If you can feel them, they should feel small, soft, and movable. Enlarged lymph nodes may feel like swollen, firm, or tender lumps, sometimes described as being pea-sized or larger.
When to Be Concerned About Groin Lymph Nodes
It’s common for lymph nodes to become temporarily enlarged due to an infection, such as a skin infection on your leg, a urinary tract infection, or a sexually transmitted infection. In these cases, the lymph nodes will usually return to their normal size once the infection clears up.
However, you should consult your doctor or healthcare provider if you notice any of the following:
- Enlarged lymph nodes that persist for more than a week or two.
- Lymph nodes that are hard, fixed in place, or rapidly increasing in size.
- Enlarged lymph nodes accompanied by other symptoms such as unexplained weight loss, fever, night sweats, or persistent fatigue.
- Redness, warmth, or pain in the area of the enlarged lymph nodes.
While enlarged lymph nodes can be a sign of infection, they can also sometimes be associated with more serious conditions, including certain cancers. It’s always best to get any persistent or concerning changes checked by a medical professional to determine the cause and receive appropriate care.
Conclusion
Understanding where your groin lymph nodes are located and how to check them is a valuable step in taking charge of your health. Regular self-exams, combined with awareness of when to seek medical advice, can contribute to early detection and timely management of any potential health issues. Remember, if you have any concerns about your groin lymph nodes, don’t hesitate to reach out to your doctor or nurse for guidance and reassurance. They are your best resource for personalized health advice.
