Proximal Hamstring Tendinopathy Treatment in Bellingham, WA
Deep buttock pain that worsens with sitting, running, or loading the hip is often the hamstring tendon at its origin — not a simple muscle strain. A targeted loading program is the foundation of treatment, with shockwave and PRP as well-evidenced options when more is needed.

Bottom line
Proximal hamstring tendinopathy is degeneration of the hamstring tendon at the sit bone — not a muscle tear and not a nerve problem, though it can be mistaken for both. A well-designed loading program targeting the hamstrings at length is the most evidence-backed approach. Shockwave has randomized trial support for active individuals, and PRP is a reasonable next step when loading has not been enough. This condition resolves slowly; a structured, patient approach produces the most durable outcomes.
The three hamstring muscles — biceps femoris, semimembranosus, and semitendinosus — share a common tendon origin at the ischial tuberosity, the bony prominence you sit on. When this tendon is repeatedly loaded beyond its capacity, it undergoes degenerative changes rather than clean inflammation. The result is chronic pain at the sit bone that is distinctly worse with sitting, especially on hard or low surfaces, and with explosive hip-loading movements like sprinting, deep lunging, and rowing.
What makes this tendon challenging to treat is that the movements that load it most — sitting, forward bending, and hip flexion under load — are difficult to avoid entirely. Aggressive hamstring stretching, one of the most common instincts when the posterior thigh hurts, compresses the tendon against the bone and often prolongs the problem rather than solving it.
Diagnostic ultrasound lets Dr. Borys visualize the tendon directly — assessing the degree of degeneration, ruling out partial tearing, and distinguishing a tendon problem from sciatic nerve involvement or referred pain from the lumbar spine, which can present in a very similar distribution.
Why patients consider this
A layered approach, led by loading
Loading Program
Tendon-specific loading — targeting the hamstrings at length, in hip flexion — is the foundation of treatment and the approach with the most consistent evidence. Getting the angles, loads, and progression right matters more than the volume of exercise.
What to expect at your visitShockwave Therapy (ESWT)
A 2024 systematic review in the British Journal of Sports Medicine found ESWT effective as a standalone treatment for proximal hamstring tendinopathy in athletes, with Level I evidence. A 2025 systematic review of hip and pelvis tendinopathies further supports its use alongside a loading program.

Ultrasound-guided PRP injection at the proximal hamstring origin is a reasonable next step when loading and shockwave have not produced adequate progress. PRP is placed directly at the tendon insertion under real-time imaging to confirm accurate placement.
Learn more about PRP therapyLoading, not rest
Complete rest does not resolve tendon degeneration — it removes the stimulus the tendon needs to remodel. The goal is to reduce provocative compression while introducing progressive loads at the angles that drive structural improvement.
The specific joint angles matter. Hamstring loading in hip flexion — not end-range stretching — is what produces the mechanical stimulus for tendon remodeling. The program is progressive and based on tendon response, not a fixed weekly schedule.
Reduce high-load hip-flexion positions
Deep hip flexion — sitting on low chairs, climbing steep hills, forward-trunk lunging — places the hamstring tendon under compressive load at its origin. Temporarily modifying these positions lets the tendon settle enough to respond to loading.
Tendon-specific loading at length
A progressive loading program targeting the hamstrings with the hip in flexion drives tendon remodeling. The specific angles and load progression matter; a generic stretching routine does not produce the same effect.
Lumbopelvic stabilization
Weakness or poor control through the glutes and lumbopelvic region increases demand on the hamstring tendon. Strengthening these proximal structures is part of a complete program and reduces recurrence.
Shockwave and PRP when loading alone stalls
When a well-executed loading program has plateaued, shockwave and PRP are evidence-supported next steps. They work best alongside continued loading — not as replacements for it.
What the research shows
Multimodal Approach Best for Proximal Hamstring Tendinopathy
Systematic review (2023) of conservative interventions found the best outcomes come from combining tendon-specific loading at length with lumbopelvic stabilization. Exercise prescription targeting combined hip flexion and knee flexion angles produced the most consistent tendon remodeling effects.

Systematic review of ESWT for athletes (British Journal of Sports Medicine, 2024) identified proximal hamstring tendinopathy as a condition with Level I evidence supporting shockwave — concluding ESWT is effective as a standalone treatment, with additional benefit when combined with a structured loading program.
View on PubMed →Shockwave Supported for Hip and Pelvis Tendinopathies
Systematic review of ESWT for hip and pelvis tendinopathies (HSS Journal, 2025) found shockwave therapy a reasonable and safe treatment option for proximal hamstring tendinopathy, with evidence supporting its use as part of a multimodal approach in patients who have not responded to conservative care alone.

What to expect over time
Load reduction and early isometrics
The first priority is calming the tendon by modifying compressive hip-flexion positions — low chairs, steep inclines, aggressive hip stretching. Isometric hamstring contractions at tolerable angles are introduced to maintain tendon stimulus without provocative loading.
Avoid prolonged sitting in deep hip flexion and refrain from aggressive stretching — both compress the proximal tendon against the ischial tuberosity and can delay recovery.
Progressive loading at length
The core of the program: progressive isotonic loading targeting the hamstrings with the hip in increasing flexion angles. Nordic curls, Romanian deadlifts, and single-leg variations are typical progressions. Load is increased as the tendon adapts.
Shockwave if indicated
For patients not progressing adequately with loading alone, shockwave is introduced in this window — typically 4–6 sessions. It is most effective alongside a continued loading program rather than as a standalone passive treatment.
If PRP is planned, it is typically placed in this window after adequate loading preparation. Post-injection soreness of 3–7 days is expected.
Return to full activity
Return to running, sport, and heavy loading is progressive and guided by tendon response. Proximal hamstring tendinopathy is a slow-resolving condition — three to six months is a realistic timeline for a meaningful reduction in symptoms, with full return to high-demand activity often taking longer.
Recurrence is common when loading is ramped up too quickly or when lumbopelvic stabilization is neglected. A maintenance program protects the gains.
Protecting your progress
Avoid aggressive hamstring stretching
Stretching the hamstring in a forward-bend position compresses the proximal tendon against the ischial tuberosity. This is one of the most common mistakes during recovery and can significantly prolong symptoms.
Sitting modifications matter
Prolonged sitting — especially on hard or low surfaces — loads the tendon at length for hours at a time. A wedge cushion that tilts the pelvis forward, or raising the seat height, reduces this compression meaningfully.
Load progression, not rest
Complete rest does not resolve tendon degeneration. Progressive loading at the right angles and intensities is what drives structural improvement. The goal is to keep the tendon working at a tolerable level throughout recovery.
Expect a long recovery window
Proximal hamstring tendinopathy is among the slower-resolving tendon problems. A three-to-six month commitment to the loading program, with patience around setbacks, is realistic and worth it.
Common questions
Start with a full hamstring tendon evaluation
Dr. Borys will confirm the diagnosis with examination and ultrasound, establish where you are in the recovery process, and discuss whether a loading program, shockwave, PRP, or a combination is the right next step.
