Symptoms of a hamstring tear include a sudden and sharp pain in the back of the thigh, according to Mayo Clinic. The athlete may hear a popping sound. The area may swell or feel tender in a couple of hours.
The hamstring tear causes an athlete to come to a complete stop if he was engaged in any activity, explains MedicineNet. The pain may be in the lower back of the thigh or just below the buttocks where the hamstring starts. The athlete may be unable to stand on the affected leg because of the pain, explains Mayo Clinic. Some athletes either hop on the good leg or fall down, reports the American Academy of Orthopaedic Surgeons. The pain is most evident when walking, bending or straightening the leg, reports WebMD.
A physical examination reveals other symptoms, such as spasms, tenderness and tightness, on the affected area, notes MedicineNet. Swelling may follow, and the area may have a black-and-blue appearance. In certain situation, a person may feel a palpable effect when he touches the muscle.
The area around the torn hamstring may appear bruised, and the athlete may experience muscle weakness, according to Mayo Clinic. The weakness in the hamstring may last for weeks, notes the American Academy of Orthopaedic Surgeons.
