A hip flexor strain refers to damage (in the form of overextension, tearing or a complete rupture) to the muscles that work together to help flex the hip joint and provide stability to the lower extremity of the body. These injuries are most commonly observed in sports that require explosive movements (e.g. soccer, football or sprinting). The typical symptoms of this injury are pain (along the front of the hip and down the front of the thigh), swelling (less commonly observed), muscle spasm and bruising.Running, jumping and even walking will become difficult with experiencing significant pain.
