Indirect Inguinal Hernia: This is a common condition in athletes, especially those involved in sports that require sudden stops, changes in direction, and rapid acceleration, which can increase intra-abdominal pressure and cause herniation through a weak point in the abdominal wall.

Inguinal Hernia: Similar to indirect inguinal hernia, any type of inguinal hernia could cause groin pain and swelling, especially if it becomes incarcerated or strangulated.
Rupture of the Inferior Epigastric Artery (IEA): Although less common, a rupture of the IEA can cause sudden onset of groin pain and swelling due to hematoma formation.
Inguinal Hematoma: Trauma to the inguinal region can result in hematoma formation, leading to pain and swelling.

Testicular Torsion: Although the primary symptom is testicular pain, it can sometimes be referred to the groin area. This condition is a surgical emergency and must be promptly diagnosed and treated to save the affected testicle.
Epididymitis or Orchitis: Inflammation of the epididymis or testis can cause severe pain and swelling in the groin area and must be treated promptly to prevent complications.

Sportsman's Hernia (Gilmore's Groin): A condition characterized by a chronic groin pain due to a weakness in the posterior wall of the inguinal canal, without a palpable hernia.
Osteitis Pubis: An inflammatory condition of the pubic bone and surrounding structures, which can cause chronic groin pain, especially in athletes involved in sports that involve kicking or rapid changes in direction.
