A hamstring strain is damage to the muscles in the back of the thigh. These muscles run from above the hip to the knee joint. A strain is a series of small tears in the muscle. The tendon attached to the muscle may also have some damage.

This problem is more common in male athletes. It is also more common in athletes whose sports involve high bursts of speed, such as running, hurdling, jumping, and kicking.
Other things that may raise the risk are:
- Prior hamstring injury
- Not warming up muscles before using them
- Muscles that are too tight or weak
- An imbalance between the hamstring and quadricep muscles
A small strain may heal in a few days. Severe strains may take a few months. Treatment may include:
- Supportive care, such as rest, ice, compression, and elevating the leg
- Crutches to keep weight off of the leg
- Medicine to ease pain and swelling
- Exercises to help with strength, flexibility, and range of motion
