High hamstring tendinopathy: when the tendon has had time to heal and the buttock still burns.

Deep, nagging pain at the sit bone that flares with running, sitting and speed. Tendons adapt slowly, but they do adapt. Here is what to ask when yours will not.

This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.

What high hamstring tendinopathy is

The three hamstring muscles run down the back of the thigh and attach at the top to the ischial tuberosity, the bony point you sit on. High hamstring tendinopathy, also called proximal hamstring tendinopathy, is a condition of that upper attachment. The tendon becomes painful and less tolerant of load, usually after a period of training it was not ready for: more miles, more speed work, more hills, or a sudden return after a break.

The classic picture is deep, localised pain at or just below the sit bone, worse with running (especially accelerating and uphill), lunging, deep stretching and sitting on hard surfaces. It is tender to press. Imaging may show thickening or small tears at the tendon, though similar changes can be found in people without pain. Other causes of deep buttock pain, including piriformis syndrome, gluteal tendinopathy, sciatic nerve irritation, hip joint problems and referred pain from the lower back, need to be considered.

Standard treatment is a progressive loading programme: isometric holds, then slow heavy strengthening, then faster and sport-specific work, over months. Tendons respond to load, not rest. Most people improve. This article is for those who have done the programme and are still stuck.

The neuroplastic contribution

Neuroplastic symptoms are real symptoms generated by learned pathways in the brain and nervous system rather than by ongoing damage in the body. Pain is an alarm the brain produces to protect you, and in a tendon problem the alarm starts for a good reason. But an alarm that has been ringing for months can learn to ring on its own. The brain comes to associate sitting, running or simply the thought of a hill with threat, and produces pain in advance. The pain is real. It is not imaginary and not 'all in your head'. And because the brain is plastic, that learning can be reversed.

The ATNS Index of Neuroplastic Symptoms does not say high hamstring tendinopathy is neuroplastic. It says that an evaluation for neuroplastic symptoms is reasonable as part of a complete assessment, and particularly worth doing when the symptoms or their course are not typical, or when the response to treatment is not what was expected. For a tendon that normally responds to a well-run loading programme in three to six months, a year of unchanged pain is the kind of course the index has in mind.

How the nervous system gets involved in a stubborn tendon:

• Fear of re-injury leads to guarding and avoidance, which keeps the tendon under-loaded and the alarm sensitive. Our guide to the fear-avoidance cycle describes this loop.
• Pain that is widespread, or that spreads down the leg without nerve signs, fits central sensitization better than a small tendon.
• Pain that flares with stress, poor sleep or a race date, rather than with load, points to the brain's threat system.

What the research shows

No study we found has measured pain sensitization in high hamstring tendinopathy itself, so the evidence here is partly direct and partly borrowed from other tendon conditions. We want to be clear about which is which.

• Hamstring-specific: a clinical commentary on individualized physiotherapy for proximal hamstring tendinopathy lists fear-avoidance beliefs as a psychosocial risk factor to look for, noting that in trials of other tendinopathies fear avoidance appears to be linked with more disability and poorer outcomes.
• Tendinopathy in general: a meta-analysis with meta-regression of pain sensitization across tendinopathies found that signs of both central and peripheral sensitization are consistently present in tennis elbow (lateral epicondylalgia), while results for other tendons, including lower-limb ones, were conflicting.
• How it is measured: a scoping review of 43 studies of pain processing in tendinopathy found wide variation in the tests used and in how patients were described, and noted that localized pain that flares with activity and eases with rest fits a tissue-based mechanism. Central involvement is not the default.

Taken together, sensitization is not the usual story in tendon pain, and the evidence is mixed. That is why the ATNS index frames a neuroplastic assessment as reasonable mainly when the course or the response to rehab is atypical, rather than as the explanation for every case.

Signs the brain may be part of the picture

• You have followed a progressive loading programme for six months or more without change.
• Pain has spread beyond the sit bone into the thigh, hip or other side.
• Scans are normal, or show the same changes on your pain-free side.
• Pain flares with stress, worry or anticipation of a run rather than with the run itself.

A solution that addresses it

Pain and symptom reprocessing is an approach built for the nervous-system part of persistent pain. It combines education about neuroplastic pain, somatic tracking (attending to the sensation with curiosity rather than dread), reducing fear and the sense of threat, a graded return to sitting, running and speed that avoids the boom-bust cycle, emotional awareness and expression, and acceptance and commitment skills. Trained clinicians deliver it, and digital programs are making it more accessible. It works alongside a strength programme, not instead of it.

Cindra is a daily AI companion built around these approaches, with daily check-ins, short practices and plain-language lessons for people whose symptoms have a neuroplastic component. If your hamstring rehab has stalled, you can join the waitlist.

What to do next

1. Get a proper assessment. A sports physician or physiotherapist should confirm the diagnosis and rule out a full tendon tear or avulsion, sciatic nerve involvement, hip joint problems and referred pain from the spine. Sudden severe pain with a pop, inability to walk, or numbness and weakness in the leg need prompt medical attention.
2. Run the loading programme properly. Progressive strengthening over months is the standard of care and resolves most cases.
3. If the course is atypical, ask the question. 'Could my nervous system be keeping this pain going?' The ATNS index says that evaluation is reasonable, especially when treatment has not worked as expected.
4. Add nervous-system work. Learn that hurt is not harm, reduce guarding, and reintroduce feared activities in steps.

This article is for general education and is not medical advice, and it does not diagnose or treat any condition. Persistent symptoms deserve a proper medical assessment to rule out disease or injury before a neuroplastic explanation is considered. If your symptoms are new, changing, or come with red-flag signs such as fever, unexplained weight loss, numbness or weakness, chest pain, or loss of bladder or bowel control, see a clinician promptly.
