Hamstring Pain

Hamstring pain is pain felt in the back of the thigh. It may start suddenly during sprinting, kicking, jumping, or changing direction. It can also build slowly with running, hill sessions, gym loading, or long periods of sitting.

Common causes include a hamstring strain, proximal hamstring tendinopathy, or pain referred from the lower back. Some people also feel hamstring-like pain from sciatica or a bulging disc.

What Is Hamstring Pain?

Hamstring pain describes pain in the back of the thigh. It may come from the hamstring muscles, the upper hamstring tendon near the sit bone, or pain referred from the lumbar spine or sciatic nerve.

Some people feel a sharp grab during sport. Others feel a deep ache, tightness, or buttock pain that worsens with sitting, hills, or faster running.

What Type of Hamstring Pain Does This Sound Like?

Sudden sharp pain during sprinting or kicking: this may suggest a hamstring strain.
High buttock pain with sitting or hills: this may suggest proximal hamstring tendinopathy.
Burning, tingling, or pain below the knee: this may suggest nerve-related pain, such as sciatica.
Recurring tightness during speed work: this may reflect strength, load, or return-to-running issues.

A physiotherapy assessment can help identify the main source and guide the right rehab plan.

What Causes Hamstring Pain?

The most common causes are hamstring strains and proximal hamstring tendinopathy. However, clinicians also screen for lumbar spine and nerve-related causes, such as sciatica.

Hamstring Strain

A hamstring strain involves damage to muscle fibres. It often occurs during sprinting, jumping, or kicking when the hamstring loads quickly at a longer muscle length. Symptoms can range from a mild grab to sharp pain, weakness, bruising, and loss of speed.

Proximal Hamstring Tendinopathy

Proximal hamstring tendinopathy usually builds over time. Pain often sits high near the buttock and sit bone. It commonly flares with repeated running, hills, deep hip flexion, and sitting on firm surfaces.

Sciatica and Referred Pain

Sciatica can mimic hamstring pain. Nerve-related pain is more likely to travel below the knee and may include tingling, numbness, or burning. By contrast, a local hamstring problem is more likely to hurt with resisted knee flexion, sprint drills, or lengthened hamstring loading.

What Are the Symptoms of Hamstring Pain?

Symptoms vary depending on the source. Muscle injuries often cause sudden pain, local tenderness, and reduced sprint speed. Tendon-related pain often causes upper hamstring or buttock pain that worsens with sitting. Nerve-related pain may travel further down the leg.

Sharp or tight pain in the back of the thigh
Pain during sprinting, kicking, jumping, or acceleration
Buttock pain near the sit bone when sitting
Reduced stride length, speed, or push-off power
Tingling, numbness, or burning if a nerve is involved

How Is Hamstring Pain Diagnosed?

A physiotherapist will assess where the pain sits, how it started, and which movements aggravate it. Your assessment may include resisted knee flexion, hip movement, lengthened loading tests, running analysis, and screening of the lumbar spine or neural tissues.

Diagnosis matters because a fresh muscle tear, an irritated tendon, and nerve-related pain often need different treatment plans. Imaging is not always needed, but it may help with severe tears, suspected tendon avulsion, or complex symptoms.

When Should Hamstring Pain Be Checked?

Book an assessment if hamstring pain keeps returning, changes your running stride, limits sprinting, or worsens with sitting. It is also worth checking if you feel tingling, numbness, burning, marked weakness, or pain below the knee.

Sudden severe pain, major bruising, or a pop near the buttock may need prompt review to exclude a more serious injury.

How Is Hamstring Pain Treated?

Hamstring pain treatment depends on whether the source is muscle, tendon, or nerve-related. Early care usually aims to settle pain, protect irritated tissue, and maintain safe movement. As symptoms settle, rehab often progresses towards hamstring strength, hip control, trunk control, and graded return to speed.

With muscle injuries, progressive loading can help restore strength and running confidence. With tendon-related pain, complete rest is often less helpful than a structured strengthening plan. Many people also benefit from eccentric strengthening, gluteal control work, and guided running progressions.

If symptoms suggest a sporting overload pattern, a sports physiotherapy review may help identify training errors, return-to-run issues, or recurring speed-load problems.

Hamstring Pain Rehab Progression

Hamstring pain rehab works best when it matches the tissue involved, your symptoms, and your activity goals. A recent strain, tendon-related pain, and nerve-related pain often need different progressions.

Stage	Main Goal	Common Focus
Early stage	Settle pain and protect irritated tissue	Gentle movement, walking tolerance, and symptom-guided loading
Strength stage	Rebuild hamstring capacity	Progressive hamstring, gluteal, hip and trunk strengthening
Running stage	Restore stride confidence	Jogging progressions, hill control, and acceleration preparation
Sport stage	Return to higher-speed demands	Sprinting, kicking, change of direction, and fatigue management

Why Does Hamstring Pain Worsen With Sitting or Speed Work?

Sitting often aggravates upper hamstring tendon pain because the tendon is compressed near the sit bone. Speed work increases load because the hamstrings must manage high force quickly, especially late in the running stride.

These patterns help separate tendon and muscle pain from spinal referral. They also guide which exercises and running drills are suitable at each stage.

Should You Keep Running With Hamstring Pain?

If pain changes your stride, limits speed, or worsens after training, reduce running load and avoid sprinting until the pattern is clearer. Mild symptoms may allow modified running, but hills, speed work, long strides, and fatigue can quickly increase hamstring load.

A staged plan usually works better than full rest or pushing through. Your physiotherapist can help set safe running limits and progressions.

When Can You Return to Running or Sport?

Return to running usually starts when walking, daily activity, and early strengthening feel controlled. The next steps often include short jogging intervals, faster running, acceleration, and sport-specific drills.

Returning too quickly can increase the risk of another flare-up. Your physiotherapist may use pain response, strength testing, running tolerance, and sport drills to guide each stage.

How Can You Reduce the Risk of Hamstring Pain Returning?

Hamstring pain can return when speed, fatigue, strength, or training load are not well matched. Prevention often focuses on building enough capacity for the task you want to do.

Build sprinting and kicking volume gradually
Use a dynamic warm-up before speed work
Include hamstring, gluteal, hip, and trunk strength
Avoid sudden spikes in hills, sprint volume, or gym loading
Plan recovery after high-speed running sessions

Hamstring Pain FAQs

How long does hamstring pain last?

Timeframes vary. Mild hamstring strains may improve within one to three weeks, while moderate strains often take four to eight weeks. Tendon-related upper hamstring pain can take longer and usually improves with consistent load management and progressive strengthening.

How can I tell if hamstring pain is sciatica?

Sciatica more often causes pain that travels further down the leg and may include tingling, numbness, or burning. Hamstring strains or tendinopathy more often reproduce with local hamstring loading, such as resisted knee flexion, sprint drills, or stretch positions.

Should I stretch if I have hamstring pain?

Stretching can help some people, but aggressive stretching can also flare symptoms. After a recent strain, heavy stretching may irritate healing tissue. With proximal hamstring tendinopathy, deep stretching can compress the tendon near the sit bone.

When should hamstring pain be checked?

Hamstring pain should be checked if it keeps returning, limits running speed, worsens with sitting, or causes tingling, numbness, or pain below the knee. Early assessment can help clarify whether the main issue is muscle, tendon, or nerve-related.

Is hamstring pain always a muscle tear?

No. Hamstring pain can come from a muscle strain, tendon irritation near the sit bone, referred pain from the lower back, or nerve-related symptoms. The pattern of pain, how it started, and what aggravates it can help identify the likely source.

Can I keep running with hamstring pain?

Some mild symptoms may allow modified running, but sprinting, hills, and fast accelerations can worsen many hamstring problems. If pain changes your stride, reduces speed, or keeps returning, pause higher-load running and seek advice.

What to Do Next

If hamstring pain keeps returning, limits your speed, or worsens with sitting, a physiotherapy assessment can help identify whether the source is muscle, tendon, or nerve-related.

Once the main driver is clear, your physiotherapist may recommend load modification, progressive strengthening, running advice, and return-to-sport checkpoints that match your symptoms and goals.
