Muscle strain: This is the most common cause of groin pain, often resulting from overuse or direct injury to the muscles in the groin area, such as the adductor muscles. Activities that involve sudden stops, changes of direction, or kicking motions are common precipitating factors.

Inguinal hernia: A protrusion of an organ or tissue through a weakened area in the groin, which can cause pain, especially when coughing, lifting, or bending.
Osteitis pubis: An inflammatory condition affecting the pubic bone and surrounding structures, often seen in athletes involved in sports that involve kicking or rapid changes of direction.
Groin pull or adductor tendinitis: Inflammation of the tendons that attach the adductor muscles to the bone, typically resulting from overuse or direct trauma.

Testicular torsion: A medical emergency where the spermatic cord becomes twisted, cutting off the blood supply to the testicle. It requires immediate attention to preserve the testicle.
Epididymitis or orchitis: Inflammation of the epididymis or testicle, often due to bacterial infection, which can cause severe pain and swelling in the groin area.
Aortic dissection or abdominal aortic aneurysm: Although less common, these conditions can refer pain to the groin area and are life-threatening if not promptly diagnosed and treated.

Avulsion fractures: A type of fracture where a fragment of bone is pulled away by a tendon or ligament, which can occur in the groin area due to forceful muscle contraction.
Psoas abscess: A collection of pus in the psoas muscle, which can cause groin pain, often associated with fever and other systemic symptoms.
Nerve entrapment syndromes: Conditions like obturator nerve or ilioinguinal nerve entrapment can cause groin pain, usually accompanied by sensory changes or weakness in the affected limb.
