Hamstring origin tendonitis is when the tendon that connects the hamstring muscle to the sitting bone (ischial tuberosity) becomes inflamed or irritated. It’s a common overuse injury, especially in runners, athletes, and people who do a lot of squatting, lunging, or sitting for long periods. It often causes deep buttock pain, especially during or after activity.

An analogy…

Think of a tendon like a rope connecting a muscle to a bone. If that rope gets tugged on too much, especially at the anchor point, it starts to fray and become sore. That’s exactly what happens in tendonitis.

What are other names that hamstring origin tendonitis can be called?

Hamstring Tendonitis, Hamstring Tendinopathy, Hamstring Tendinitis, Hamstring Origin Tendonitis

What causes hamstring origin tendonitis?

The hamstrings are a group of muscles at the back of your thigh that attach to the ischial tuberosity, the bone you sit on. Repetitive strain or overload, especially from hip flexion combined with knee extension (like running, lunging, or deadlifting), can cause micro-tears and inflammation in the tendon at its origin. This leads to pain, stiffness, and reduced function.

What are the signs and symptoms of hamstring origin tendonitis?

• Deep, aching pain in the lower buttock, near the sit bone
• Pain that worsens with running, squatting, lunging, or prolonged sitting
• Tenderness when pressing on the hamstring attachment point
• Stiffness or pain first thing in the morning or after rest
• Pain may refer down the back of the thigh, but usually not below the knee
• Discomfort when stretching the hamstring or leaning forward with a straight leg

What tests are used to diagnose on hamstring origin tendonitis?

Palpation: Pressing on the ischial tuberosity reproduces pain

Active and passive stretch tests: Pain with straight leg raise or hip flexion

How long does hamstring origin tendonitis take to heal?

Mild to moderate cases often improve in 6 to 8 weeks with load management and rehab. More chronic or recurring cases may take 3 to 6 months to fully resolve.

• Repetitive running, sprinting, or kicking
• Sudden increase in training intensity or volume

• Prolonged sitting or poor posture
• Incorrect form during deadlifts, lunges, or squats

What treatment can help hamstring origin tendonitis?

• Relative rest from aggravating activities
• Manual therapy (massage, dry needling, soft tissue release)
• Progressive loading exercises
• Postural retraining and movement correction
• Shockwave therapy
