Pain in the left groin area may indicate a ligament, tendon or muscle strain, according to Mayo Clinic. Groin pain is typically a result of an injury due to increased activity, exercise or participation in sports.
Left groin pain may also indicate a hernia, kidney stones, bone fracture or injury, or a testicle condition, according to Mayo Clinic. In some men, a condition known as avascular necrosis, which is the death of bone tissue due to limited blood flow, can cause left groin pain.
Joint and testicle inflammation as well as swelling of the scrotum are often accompanied by groin pain, according to Mayo Clinic. In some cases, individuals with an inguinal hernia, pinched nerve or osteoarthritis may experience pain in the groin area. Some diseases, such as the mumps, swollen lymph nodes, testicular cancer and tendinitis, can cause pain within the groin, in addition to urinary tract infections.
A man experiencing left groin pain should be screened to rule out scrotal masses, enlarged veins in the scrotum or a retractile testicle, which is a testicle that moves between the abdomen and scrotum, according to Mayo Clinic. A twisted groin, strain or fracture is the most common cause and requires rest to decrease the risk of prolonging the injury.
