Musculoskeletal strain: This is often the most common cause of groin pain in females, resulting from overuse or direct injury to the muscles and tendons in the groin area. Activities that involve sudden stops, changes of direction, or kicking can lead to this condition.

Hernia (inguinal or femoral): Although more common in males, females can also experience hernias, which occur when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The symptoms can include groin pain, especially when coughing, lifting, or bending over.
Ovarian cysts or torsion: Ovarian cysts are fluid-filled sacs on the ovary that can cause pain if they rupture or if the ovary becomes twisted (torsion). The pain is usually sharp and can be accompanied by nausea, vomiting, and fever.
Endometriosis: This condition involves tissue similar to the lining inside the uterus growing outside of it, leading to pain, especially during menstrual periods. The pain can be localized to the groin area among other places.
Urinary tract infections (UTIs) or kidney stones: While these conditions primarily affect the urinary system, they can cause pain that radiates to the groin area. UTIs can cause a burning sensation during urination and frequent urination, while kidney stones can cause severe, crampy pain.

Ectopic pregnancy: Although less likely, an ectopic pregnancy (where the embryo implants outside the uterus) is a medical emergency that can cause severe abdominal or groin pain, especially if the ectopic pregnancy ruptures. It's crucial to consider this in any female of childbearing age presenting with acute groin pain.
Appendicitis: While the appendix is typically located in the lower right abdomen, an inflamed appendix can sometimes cause pain that is perceived in the groin area, especially if the appendix is located in a retrocecal position (behind the cecum).
Diverticulitis: Inflammation of the diverticula in the digestive tract can cause severe pain, usually in the lower left abdomen, but can sometimes be felt in the groin.

Avulsion fractures: These are fractures that occur when a fragment of bone tears away from the main mass of bone as a result of physical trauma, which can happen in the groin area due to severe stress on the muscles and bones.
Nerve entrapment syndromes: Conditions like meralgia paresthetica (entrapment of the lateral femoral cutaneous nerve) can cause pain, numbness, or tingling in the groin area, although these are less common causes of groin pain.
Tumors (e.g., sarcomas): Although rare, tumors of the soft tissues or bones in the groin area can cause pain and should be considered in the differential diagnosis, especially if the pain is persistent and unexplained by more common causes.
