Hamstring Injury


A hamstring injury

is a bruise, strain, or tear to a hamstring muscle. Your hamstring muscles are in the back of your thigh and help bend and straighten your leg.

Common signs and symptoms:

You may start to feel symptoms when you rest after activity. You may have any of the following:

  • Pain, swelling, or bruising
  • Feeling a pop or tear
  • Trouble bending or straightening your leg
  • Loss of strength


may include any of the following:

  • Medicines can help decrease pain and swelling.
  • Surgery may be needed if you have a severe strain or tear. You may also need surgery if you have pain or tightening that does not go away.

Seek care immediately if:

  • Your lower leg or foot is pale or blue, and feels cool when you touch it.
  • You have severe pain.
  • You cannot bend or straighten your leg.

Call your doctor if:

  • You have a fever.
  • Your signs and symptoms do not improve with treatment.
  • You have questions or concerns about your condition or care.


  • Rest your hamstring muscles as directed.
  • You may need to use crutches until you can put weight on your injured leg without pain. This will help decrease stress and strain on your hamstring muscles.
  • Apply ice on the back of your thigh for 15 to 20 minutes every hour or as directed. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel before you apply it. Ice helps prevent tissue damage and decreases swelling and pain.
  • Wear an elastic bandage to help decrease swelling. It should be snug but not tight.
  • Elevate your leg above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your leg on pillows or blankets to keep it elevated comfortably.

  • Go to physical therapy, if directed. A physical therapist teaches you exercises to help improve movement and strength, and to decrease pain.

Prevent another hamstring injury:

  • Ask when you can return to your usual activities. You may injure your hamstring muscles more if you start activity too soon.
  • Warm up and stretch before and after you exercise. This helps loosen your muscles and decrease stress on your hamstring muscles. Slowly increase time, distance, and how often you train. A sudden increase may cause injury.

Follow up with your doctor as directed:

Write down your questions so you remember to ask them during your visits.
