Causes of groin and leg pain in women include lymph nodes that are swollen, kidney stones and obstructive uropathy, according to Healthline. Other causes related to the pain are hernias, sprains and strains, and abdominal aortic aneurysms.
The lymph nodes are glands that can swell in response to infections and tumors, causing pain in both the groin and legs, Healthline explains. An individual has obstructive uropathy when the flow of urine is blocked and gets back to the kidneys, causing a blockage in either of the ureters. Another cause is kidney stones, which are substances originating from the kidney or solid masses arising from crystallized calcium that can penetrate the urinary tract.
When an organ pushes past the tissue or muscle that holds it in place, the situation is called a hernia, which is a common cause of pain in the abdomen, belly button, groin and upper thigh regions, as noted by Healthline. Strains and sprains are body injuries resulting from physical activities. They can either be minor or severe, depending on the incident that takes place at the time of injury. The aorta carries blood from the heart to the abdomen, legs and pelvis. Bulging or swollen aortic walls around the abdomen, known as abdominal aortic aneurysms, can also cause pain.
