A lump or swelling in the groin can appear gradually or suddenly. It may be painless, tender or associated with a dragging sensation, particularly when standing, coughing, lifting or exercising. Although several conditions can cause a groin lump, an inguinal or femoral hernia is an important possibility. Women should receive an accurate assessment because femoral hernias can be less obvious and may carry a higher risk of becoming trapped.
What can cause a groin lump?
A hernia develops when fat or part of the bowel pushes through a weakness in the lower abdominal wall. An inguinal hernia usually appears higher in the groin, while a femoral hernia tends to sit lower, near the upper thigh. Other possible causes include enlarged lymph nodes, a cyst, a lipoma, inflammation or a vascular problem. The location and appearance alone may not be enough to identify the cause.
Symptoms that may suggest a hernia
A hernia lump may become more noticeable when you cough, strain or stand and may reduce when you lie down. You may also experience aching, pressure, burning or discomfort during activity. Some hernias are small and difficult to see, while others produce a clear bulge. Symptoms can overlap with hip, pelvic or muscular conditions, so persistent discomfort should not be self-diagnosed.
How is a groin lump assessed?
Your surgeon will ask when the lump appeared, whether it changes with movement and if you have pain or digestive symptoms. Examination is usually performed while standing and lying down, sometimes while you cough. Ultrasound or other imaging may be recommended when the diagnosis is uncertain, the lump is not clearly visible or a femoral hernia is suspected.
When should I seek urgent help?
Seek urgent medical attention if the lump becomes suddenly painful, firm or cannot be pushed back, particularly if you also have vomiting, abdominal swelling, fever or difficulty passing stool or wind. These symptoms can indicate that tissue is trapped or its blood supply is affected.
What treatment may be offered?
Treatment depends on the diagnosis, symptoms and risk of complications. A confirmed groin hernia may require surgical repair, while another type of lump may need different investigation or treatment. A specialist consultation provides a clear diagnosis and an individual plan rather than assuming that every groin lump is a hernia.
Frequently asked questions
Can a groin hernia disappear on its own? A true hernia does not usually close by itself, although the lump may temporarily reduce.
Should women have groin hernias checked? Yes. Assessment is important to distinguish inguinal from femoral hernias and rule out other causes.
Can I exercise with a groin lump? Avoid activities that worsen pain until the cause has been assessed. Sudden severe symptoms require urgent care.
