Have you ever felt a popping sensation at the back of your thigh, followed immediately by severe pain, while engaging in your favorite sporting activity? Or did you feel a sudden, sharp pain below your buttocks that made it difficult to walk or bend over? Have you ever felt severe spasms and bruising on your posterior thigh after an intense workout session at the gym? You probably sustained a hamstring injury.

The hamstrings are the organization of three muscle tissues behind your thigh that generally run from out of your hip to just under your knee. They assist in bending your knee and are used while participating in sports like sprinting, jumping, or hiking. Hamstring accidents are sprains or tears to the big group of muscles and the tendons behind the thigh that arise whilst they're stretched past their regular limits. They are not uncommon amongst athletes that play football, tennis, and basketball, in addition to runners and dancers.

What Causes Hamstring Injury?

There are numerous aetiologies, however, a number of the widespread ones include:

High-energy sports, e.g., sprinting, skating, dancing: sports that require unexpected effective moves tend to hurt the muscles.

Overuse of muscle tissues without intermittent relaxation intervals: the use of the muscle tissues for a prolonged time without brief intervals of relaxation fatigues them and will increase their capacity for harm.

Previous hamstring harm: someone who has had an episode in their early years is vulnerable to a reoccurrence, mainly if it was not expertly managed.

Poor flexibility is a frequent cause in newbie athletes. Flexibility is the capacity of the muscle tissues to stretch without difficulty, and athletes with terrible muscle conditioning are at risk of strains.

Direct trauma to the thigh: this happens in contact sports activities, i.e., football and basketball. An unexpected direct hit to the hamstrings can instantly injure them, with a serious outcome.

Tight anterior thigh muscle tissues: An imbalance between the posterior and anterior thigh muscle tissues causes the hamstrings to overstretch during strenuous sports. This then leads to a rupture of the fibers of the hamstrings.


This may be categorized into three levels based on how the person rates the pain, decreased muscle power, and lack of motion in that area. They include:

Grade 1 (mild): a minor muscle pull. The person might also come down with an ache and swelling but will nevertheless be capable of using the leg.

Grade 2 (moderate): there may be a partial muscle tear that can cause widespread pain and swelling. There can also be bruising. This is due to bleeding into the muscle mass and will appear as a discoloration.

Grade 3 (excessive): there may be a total tear of the muscle tissues, and you may not be able to walk. This is followed by an excruciating ache, mainly whilst you attempt to put your entire body weight on the affected leg or take a few steps.

Symptoms of Hamstring Injuries

The symptoms of a hamstring injury vary depending on the severity of the injury. However, some common symptoms of hamstring injuries include:

  • Pain in the back of the thigh: Pain is the most common symptom of hamstring injuries. The severity of the pain can range from mild discomfort to a sharp, stabbing pain.
  • Swelling and bruising: Swelling and bruising around the injured area can occur, particularly in severe hamstring injuries.
  • Difficulty walking or standing: Hamstring injuries can make it difficult to walk or stand due to pain and weakness in the affected leg.
  • Limited range of motion: Limited range of motion in the hip and knee joints is another symptom of hamstring injuries.


Diagnosis is often made by a Medical officer or Physical Therapist.

You will be asked a few questions to know the mode of occurrence. This allows an accurate diagnosis, as some other ailments cause aches in the region of the posterior thigh just as well.

A bodily examination will be done to test for swelling and tenderness. The doctor will palpate the whole length of the muscle and this may bring about the return of the pain. The affected limb can also be moved into numerous positions. The depth of your ache and sensitive points in the muscles will decide the severity of harm and the most efficient management procedures.

Some investigations, such as imaging, can be required to verify the extent of harm, e.g., x-rays, ultrasounds, or magnetic resonance imaging(MRIs).

Hamstring Injury Treatment at Home

Treatments can be done at home using the RICE therapy method as the first line of management, before consulting a physician.

  • Rest: relax the leg and avoid standing on it. The use of crutches or cane could help to prevent using the leg.
  • Ice: To reduce inflammation, apply ice for about 15 minutes every 3-4 hours. However, don't put naked ice on the skin. The ice needs to be wrapped in a towel to prevent frostbite.
  • Compress: use a compression bandage or compression shorts to reduce swelling.
  • Elevate yourself with a pillow while reclining or sitting. In a reclined position, the leg needs to be raised above the level of the heart. This, additionally, reduces the swelling and accelerates the process of healing.
  • Gentle exercises, once the pain and swelling have subsided Exercises such as bending and straightening the legs whilst in supine or sitting positions, strolling, and biking may also be carried out.

Prevention of Hamstring Injuries

Preventing hamstring injuries is crucial for endurance athletes to maintain their performance and avoid long periods of time off due to injury. Some prevention strategies for hamstring injuries include:

  • Proper warm-up and cool-down: Warming up before exercise and cooling down after exercise can help prepare the muscles for activity and prevent injury.
  • Stretching: Regular stretching can help increase flexibility and reduce the risk of injury.
  • Strengthening exercises: Strengthening exercises that target the hamstring muscles, such as leg curls, can help prevent hamstring injuries.
  • Gradual increase in training: Endurance athletes should gradually increase their training intensity and volume to prevent overuse injuries.
  • Proper footwear: Wearing proper footwear that provides support and cushioning can help reduce the risk of injury.

Acupunture for Hamstring Injuries

Champ de Fleurs is an acupuncture mat that can be used to alleviate pain and promote healing in various parts of the body. When it comes to hamstring injuries, using the Champ de Fleurs mat can help to improve blood circulation in the affected area, which can promote faster healing and reduce inflammation. The mat's small, pointed needles can stimulate the muscles and release tension, which can help to reduce pain and stiffness in the hamstring muscles. Additionally, the Champ de Fleurs mat can help to promote relaxation, which can be beneficial for individuals who may be experiencing muscle spasms or tightness in the hamstring muscles.

Risk Factors in Endurance Athletes

Endurance athletes are at an increased risk of developing hamstring injuries due to the demands of their sport. Some risk factors for hamstring injuries in endurance sports include:

  • Overuse: Overuse injuries can occur when an athlete trains too hard or too often without giving their muscles enough time to rest and recover.
  • Muscle imbalance: Muscle imbalances, particularly between the quadriceps and hamstring muscles, can increase the risk of hamstring injuries.
  • Poor form: Poor running or cycling form can put extra stress on the hamstrings and increase the risk of injury.
  • Fatigue: Fatigue can lead to poor form and muscle imbalances, which can increase the risk of injury.
  • Previous injury: Athletes who have previously suffered from hamstring injuries are at an increased risk of re-injury.
  • Age: Older athletes may be at a higher risk of hamstring injuries due to decreased muscle flexibility and strength.
  • Muscle tightness: Tight muscles, particularly in the hamstring and hip muscles, can increase the risk of injury.


Hamstring injuries are a common injury in endurance sports, particularly in runners, triathletes, and cyclists. These injuries can significantly impact an athlete's performance and sideline them for an extended period. It is crucial for endurance athletes to understand the definition of hamstring injuries, common symptoms, home treatment options, prevention strategies, and risk factors. Preventing hamstring injuries through proper warm-up and cool-down, stretching, strengthening exercises, gradual training intensity, proper footwear, and proper form can help athletes avoid the injury and maintain their performance. It is important to seek medical attention for severe hamstring injuries and to follow a rehabilitation program to prevent re-injury.
