Pain in the groin after working out strenuously can be due to a number of injuries to structures of the lower abdomen and pelvis. You may have strained a muscle tendon or ligament that passes through the pelvis. You may also be developing a hernia. If there is an ache that continues to occur after rest, see your primary care physician for further evaluation.
The most common cause of groin pain is muscle, tendon or ligament strain. Groin pain may occur immediately after an injury, or swelling may come on gradually over a period of weeks to months. Several muscle groups in the hip and pelvis provide your lower extremity with a wide range of movements. Overuse and irritation of these muscles can lead to muscle strain. Muscle strain occurs when there is a muscle fiber tear secondary to overstretching of the injured muscle.
An inguinal hernia is a bulge in the groin area on either side of your pubic bone, which may also include pain or discomfort in your groin during exercise. This bulge occurs due to a sac protruding through a hole or weak area in the layer of the abdominal wall that surrounds the muscle.
A fracture of a bone in the pelvis can result in pain that refers to the groin region. The hip can no longer adequately provide the socket needed for the femur to move freely. Pain can cause limited range of motion and inability to walk properly.
Further Evaluation Needed
Pain in the groin may be a benign occurrence, but you should have this problem investigated by your physician. Swelling can grow in size and lead to pain. If you cannot bear weight on the leg on the same side where you are experiencing groin pain, you may need medical imaging of your hip and pelvis.
