A hamstring strain is an injury to the muscles at the back of the thigh, and it is one of the most common injuries in running and sprinting sports. It can range from a minor niggle to a more significant tear, and it has a particular reputation for recurring if not rehabilitated properly — which is exactly why a sensible, graded recovery matters so much. At Back in Action in Penwortham, we care for people across Preston and Lancashire recovering from hamstring injuries.
Understanding hamstring strains
The hamstrings are a group of three muscles running down the back of the thigh, from the base of the pelvis to below the knee. They bend the knee and extend the hip, and they are under particular strain during fast running, when they work hard to control the leg as it swings forward and decelerate it before the foot lands. It is in this rapid lengthening under load that they are most often injured. A strain occurs when the muscle or tendon is stretched or loaded beyond its capacity — classically during sprinting or a sudden stretch — overstretching or tearing some of the fibres.
Hamstring strains are graded by severity, from a mild grade-one overstretch through a partial grade-two tear to a more significant grade-three injury. What sets hamstring injuries apart is their tendency to recur: a poorly rehabilitated hamstring is significantly more likely to be injured again, which is why rebuilding strength fully before returning to sprinting is so important.
This reputation is well earned — hamstring injuries are among the most common and most frustrating in sport precisely because they so often come back. The good news is that this is largely preventable: a thorough rehabilitation that rebuilds strength through the muscle’s full length, and at speed, dramatically reduces the chance of a repeat. Doing the rehabilitation properly the first time is, in effect, the best treatment for the next injury.
What a hamstring strain can feel like
Symptoms centre on the back of the thigh and include:
- A sudden sharp pain at the back of the thigh, often during sprinting
- Pain when bending the knee against resistance, or when stretching the hamstring
- Tenderness, and sometimes swelling or bruising, at the back of the thigh
- Tightness, weakness or a feeling that the leg cannot be trusted at speed
- Pain with running, lunging or bending forward
- Tenderness along the back of the thigh, sometimes with bruising appearing a day or two later
Most people can recall the exact moment of injury, typically while running or accelerating, which helps distinguish a strain from a gradually building problem.
Common causes and risk factors
Hamstring strains are usually triggered by a specific movement, against a background of contributing factors:
- Sprinting and fast running, particularly when accelerating
- Inadequate warm-up before vigorous activity, particularly fast running
- Poor flexibility or limited strength at longer muscle lengths
- Muscle fatigue, or a sudden increase in training intensity or frequency
- Weakness or imbalance between the hamstrings and the thigh muscles at the front
- A previous hamstring injury, which markedly increases the risk of another
- Returning to sprinting too soon after a previous strain, before strength has rebuilt
Understanding what led to the injury helps us guide your recovery and, importantly, reduce the high chance of recurrence that hamstring injuries carry.
When to seek help
Most hamstring strains settle with sensible care, but proper rehabilitation is especially important here given the risk of recurrence. Please seek prompt medical attention if you felt a severe tearing at the time with significant swelling or bruising and cannot bear weight, or if you felt a sudden sharp pain high up where the hamstring meets the pelvis, which can indicate a more significant injury that should be assessed.
How long does a hamstring strain take to heal?
Recovery time depends on the grade. A mild strain may settle within a couple of weeks, while a more significant tear can take six weeks or considerably longer. The crucial point with hamstrings, though, is not just the time but the quality of the rehabilitation. Because re-injury is so common, returning to sprinting before strength has been fully rebuilt is a frequent and frustrating cause of repeated injury. A patient, thorough, graded return — rebuilding strength through the full range and at speed — gives the best protection against it happening again.
How chiropractic care can help
Chiropractors care for many people recovering from muscle strains. In the early stage, our hands-on, drug-free care focuses on settling symptoms and protecting the healing tissue. As recovery progresses, the emphasis shifts firmly to a graded rehabilitation programme to rebuild strength and flexibility — particularly important for the hamstring — alongside soft-tissue work and mobilisation of the hip, pelvis and lower back where helpful. Because we are a multi-practitioner clinic, we can also draw on physiotherapy and sports therapy, which are well suited to guiding a safe return to sport. We will be honest about what care can offer and refer you on where appropriate.
What to expect at Back in Action
Your first visit is mostly about understanding your injury — how it happened, how it is behaving, and what you need to return to. We will carry out a physical examination of the thigh, hip and pelvis, and explain what we have found in plain language. We pay particular attention to a pain felt high up where the hamstring attaches to the pelvis, as injuries there can behave differently and occasionally need further assessment. You can read more on our new patients page, with current charges on the fees page. We will set realistic expectations, place particular emphasis on a thorough return-to-sport plan, and review your progress as we go.
Helping yourself: self-care and recovery
Your own role is central in recovering well from a hamstring strain and avoiding a repeat:
- In the early days, ease off aggravating activity and avoid pushing through sharp pain
- Let the most painful early phase settle, then begin strengthening rather than relying on rest alone
- Keep gently active within comfortable limits as symptoms allow
- Commit to a progressive strengthening programme, even once the pain has gone
- Return to sprinting only once strength has rebuilt across the full range and at speed
- Warm up properly, and build running loads gradually rather than in sudden jumps
If you would like guidance tailored to you, we can build a safe, progressive exercise and return-to-sport plan around your recovery, with particular attention to the strength work that protects against re-injury.
Related conditions and treatments
A hamstring strain is closely linked to thigh muscle strain, quadriceps strain, groin and thigh pain and other recurrent injuries. The care we provide draws on approaches such as exercise and rehabilitation and chiropractic manipulation, and may form part of a wider plan alongside our chiropractic, physiotherapy and sports therapy services.
