Understanding That “Pain in the Butt” Injury
Proximal hamstring tendinopathy (PHT), often called a high hamstring injury, is a stubborn overuse injury common in runners. It usually starts as a deep ache near the “sit bone” and as every tendon injury often hurts at the beginning of a run, then eases as you warm up. resting it for longer periods, driving or even stretching can be surprisingly uncomfortable.
The hamstrings are a group of three muscles that help bend the knee and extend the hip, making them work constantly during running. Because they attach near the pelvis and cross two joints, they take a lot of stress. When training loads increases the tendon can become irritated.
This injury is often less about a single strain and more about repeated small injuries. Tiny micro-tears happen normally, but without enough recovery, the tendon fibers can become painful. That’s why PHT is usually considered a training error.
Common Signs to Watch For
Symptoms usually come on gradually, not suddenly. You may feel:
- Deep ache high in the back of the thigh or buttock
- Tenderness when pressing on the sit bone
- Pain during running, stairs, or prolonged sitting
- Discomfort when stretching the hamstring
- Sometimes pain that travels down the leg
A good rule: if you have bruising, major swelling, or pain waking you at night, it may be more than tendinopathy and should be assessed professionally.
Healing Means Loading, Not Resting Forever
The biggest mistake people make is either pushing through too hard or doing endless stretching. Surprisingly, aggressive stretching often irritates this injury more.
Recovery usually works better with progressive loading—gradually strengthening the tendon so fibers realign and tolerate force again.
Running may still be possible, but only if pain stays very low. A gentle return-to-run plan might begin like this:
- 5-minute walk warm-up
- 1 minute easy run + 4 minutes walk
- Repeat 5–6 rounds
- 5-minute walk cool-down
Do this every other day and increase running intervals slowly if symptoms stay calm. The focus early is volume, not speed.
Recovery can take months, sometimes longer, so be patient
Friendly Exercises to Rebuild Strength
1. Hamstring Isometric Holds
Lie in a bridge position and dig one heel into the ground.
- Hold 10–20 seconds
- 5 holds
- 2–3 sets
This can reduce pain while building early tendon tolerance.
2. Hip Thrusters
With shoulders supported on a bench or chair:
- Lift hips upward by squeezing glutes
- Lower slowly
- 2–3 sets of 10–15 reps
Great for building glutes and unloading the hamstrings.
3. Banded Glute Walks
Place a resistance band above the knees.
- Take controlled steps forward and backward
- Stay in a mini squat
- 2–3 sets of 10–15 reps
Strong hips often reduce stress on irritated hamstrings.
4. Eccentric Deadlifts
This is a key strengthening exercise.
- Hinge slowly from the hips
- Keep slight bend in knees
- Lower with control, then return upright
- 2–3 sets of 8–12 reps
The slow lowering phase is what helps the tendon adapt.
