If you have pain in the inner, upper thigh where it meets the lower abdomen, you have groin pain. There are several causes of groin pain.
The most common cause is a strain of the muscle, tendon or ligament in the groin area. This occurs commonly in athletes who play football, soccer, or hockey. It can occur right after the injury or can develop gradually with repeated use of the area that is injured. Sometimes, there may be a hernia, bone injury, facture, or kidney stones that may cause the groin pain. Sometimes, a problem with the testicles can cause pain in the groin area as well. These reasons are less common than a strain in the groin region.
