The American Academy of Orthopaedic Surgeons mentions these common symptoms of hamstring injury:

  • A severe and sudden pain in the back of the thigh, particularly if running at full speed.
  • Swelling of the hamstring that usually appears within a few hours of the injury.
  • A discoloration of the skin that appears below the back of the knee within a few days of the injury.
  • Feeling that the hamstring muscle is weak.
