A pulled groin muscle or groin strain is a type of injury that affects the muscles involved in adduction, or pulling the legs together. There are three groin muscles that run from the upper region of the inner thigh down to the inside of the knee. People who develop symptoms of this muscle injury, such as groin pain, bruising or stiffness, should consult a doctor to determine the cause of the pulled groin muscle.
Sudden Stress on Groin
Sudden stress placed on the groin muscle can cause this tissue to tear or pull apart. This common cause of a pulled groin muscle most frequently affects athletes who participate in sports that require abrupt or quick bursts of speed, such as basketball, hockey, soccer, football or rugby, according to the New York University Langone Medical Center.
Overstretching of Groin
Overextending or overstretching the groin muscle can also cause this type of injury. Stretching the groin muscle beyond its limit can occur during activities such as jumping or kicking, North Avenue Beach Sports reports. When this occurs, the muscle fibers in the groin rip apart, causing groin pain and weakness in affected people.
Overuse of Groin
A pulled groin muscle can occur as a consequence of overusing this muscle, NYU Langone Medical Center warns. Frequent use of the groin can tighten or contract these muscles, making them more susceptible to injury.
Trauma to the Groin
Direct trauma or injury to the groin can cause a pulled groin muscle. Depending upon the force of the trauma, the groin muscle can sustain a partial or full tear. This type of injury typically occurs during athletic events when athletes collide with each other.
