Hamstring Injury: Causes, Symptoms & Treatment

Thanks to extensive TV coverage of sports, hamstring injuries are now widely recognized by the public as one of the most recognized sports injuries.

What is the Hamstring:

The hamstring is a group of three muscles located along the back of the thigh, running from the pelvis down to just below the knee. The hamstrings help to:

• Bend the knee
• Straighten the hip
• Walk, run, jump, and climb stairs
• Maintain balance and posture

What is a Hamstring Injury?

A hamstring injury is a muscle strain that affects the hamstring muscles at the back of the thigh. Hamstring injuries are mostly hamstring strains, pulled hamstrings or torn hamstrings. The severity of hamstring injury ranges from a mild strain to a complete muscle or tendon rupture. A hamstring injury occurs when one or more of these muscles are:

• Overstretched
• Partially torn
• Completely torn

What Causes a Hamstring Injury?

Hamstring injury is usually a sports injury, one of the most common ones. Any activity that puts too much force on the hamstrings can cause injury. The hamstring muscles are made of lots of small fibres woven together. When too much force is applied, it pulls them longer than they can stretch. But it can also happen anytime when something puts more force on the hamstrings and they are unable to tolerate it. Higher-grade hamstring injuries can happen when a person slips and falls. Sliding on ice or wet ground can make you do “the splits” as you land and tear your hamstring muscles

• Sudden sprinting or rapid acceleration
• Jumping or kicking sports
• Sudden changes in direction
• Inadequate warm-up before exercise
• Muscle fatigue
• Tight hamstring muscles
• Weak thigh or hip muscles
• Previous hamstring injuries
• Poor flexibility
• Falls or direct trauma

The most common hamstring muscle injury symptoms include:

• A bump or knot in the muscle that can be seen or felt
• Bruising
• Feeling or hearing a pop - more common with higher-grade injuries
• Muscle spasms
• Muscle stiffness
• Pain on the back of the thigh -especially during movement
• Pain where the hamstring meets the buttocks while sitting down
• Swelling
• Tenderness
• Trouble moving the leg

The pain from a hamstring injury may spread or radiate from the back of the leg into the groin, buttock or other parts of the leg

Diagnosis and Tests

A healthcare provider can usually diagnose a hamstring injury with a physical exam. Imaging tests provide a detailed study about the injury:

• An X-ray will show any damage to the bones where the hamstring connects
• You may need an MRI or ultrasound to show how injured your hamstring is
• Physical examination
• Assessment of muscle strength and flexibility
• Ultrasound
• MRI scan to determine the location and severity of the tear

TREATMENT FOR HAMSTRING INJURY

For mild to moderate injuries treatments may include:

• Rest from strenuous activities
• Ice packs for 15–20 minutes every few hours during the first 48 hours
• Compression bandage
• Elevation of the leg
• Pain-relieving and anti-inflammatory medications (as advised by your doctor)
• Physiotherapy
• Stretching exercises
• Progressive strengthening exercises
• Balance and flexibility training

For serious injuries

• The MEAT method. MEAT stands for Movement, Exercise, Analgesia and Therapy
• The RICE method. RICE stands for Rest, Ice, Compression and Elevation
• Physical therapy  
• Hamstring surgery

Surgery followed by rehabilitation may be recommended when:

• The hamstring tendon has completely torn away from the bone
• There is a complete muscle rupture
• Conservative treatment has failed
• High-performance athletes require optimal restoration of function

Preventing hamstring injuries involves a combination of strategies:

• Warm-Up and stretching: Engaging in a proper warm-up routine before physical activity can enhance flexibility and reduce injury risk
• Strength training: Incorporating strength training exercises targeting the hamstrings and surrounding muscles can improve overall stability
• Proper footwear: Wearing appropriate shoes for specific activities can help prevent injuries
• Hydration and Nutrition: Staying hydrated and maintaining a balanced diet rich in essential nutrients supports muscle health

Recovery focuses on:

• Pain control
• Restoring flexibility
• Regaining muscle strength
• Improving balance and coordination
• Sport-specific training before returning to activity

The Importance of Rehabilitation: Returning to sports too early significantly increases the risk of re-injury
