Hip Flexor Strain

A hip flexor strain can range from a minor pull to something that sidelines you for weeks, and how you manage it early makes a real difference. Our Burlington clinic can help you understand what you are dealing with and get you back to full strength.

What Is a Hip Flexor Strain?

The hip flexors are a group of muscles at the front of the hip that lift the thigh toward the body and play a central role in walking, running, kicking, and changing direction. When these muscles get overstretched or overloaded, a strain can occur anywhere along the muscle or where it attaches to the bone.

Hip flexor strains typically show up as pain or tightness at the front of the hip or groin, often with a sharp sensation during the moment of injury followed by ongoing achiness with movement. Activities like sprinting, kicking, or a sudden change in direction are common triggers, but strains can also develop gradually from overuse without any single incident.

In some cases the injury is straightforward. In others the pain lingers longer than expected because the muscle was not given the right conditions to heal, or because the underlying cause, whether that is weakness, tightness, or a change in training volume, was never fully addressed.

It is also worth knowing that hip flexor pain does not always mean a muscle strain. The hip joint, the sacroiliac joint, and the lumbar spine can all refer pain into a similar area. Understanding what is actually driving your hip pain matters because the management of each is quite different.

A proper assessment looks at muscle strength and length, how the hip moves, and what specifically provokes your symptoms, so we can confirm what is going on and put together a plan that actually addresses it.

What Leads to a Hip Flexor Strain

Hip flexor strains do not always happen from one big moment. More often they develop when the muscle has been repeatedly asked to do more than it is ready for, whether from a sudden spike in training or from chronic tightness that was never properly addressed.

Common causes include:

A sudden explosive movement like sprinting, kicking, or jumping that overloads the muscle in one go
A rapid increase in running volume or training intensity without enough time to adapt
Tight hip flexors that were already operating near their limit before the injury occurred
Weakness in the surrounding muscles like the glutes and core that shifts more demand onto the hip flexors

Repetitive hip flexion movements in sport or at work that gradually wear the muscle down over time
Returning to full activity too quickly after a previous hip or groin injury that was not fully rehabbed
Prolonged sitting that keeps the hip flexors in a shortened position, reducing their ability to handle sudden demand
Poor movement patterns during running or lifting that place excessive strain on the front of the hip

How We Assess a Hip Flexor Strain

Because pain at the front of the hip can come from the muscle itself, the hip joint, the lumbar spine, or the groin, the assessment starts with a detailed conversation. When did it happen, what were you doing, where exactly does it hurt, what makes it worse, and has anything like this happened before. The answers help us narrow down what is actually injured.

From there we look at how the hip is moving and how the hip flexor is functioning. That means testing muscle strength, length, and provocation, checking whether specific movements or positions reproduce your symptoms, and assessing how the hip loads during walking and more demanding activities. Grading the strain accurately is an important part of this, because a minor strain and a significant tear are managed very differently.

The lower back, pelvis, and groin are assessed as well. Because these regions are closely connected to the hip flexor complex, tightness or dysfunction in one area can influence how the hip flexor is being loaded and why it got strained in the first place.

Rather than treating the pain location and hoping for the best, the goal is to understand the full picture of what happened and what is needed to get the muscle back to full strength. Imaging is not always necessary but may be considered if the injury appears significant or is not responding as expected.

Treating a Hip Flexor Strain

Getting the Muscle Healthy and Back to Full Strength

Treatment starts with understanding what you want to get back to, whether that is returning to sport, getting through a training session without pain, or just walking up stairs without that familiar pull at the front of your hip.

Because hip flexor strains vary considerably in severity, treatment is shaped around where you are in the healing process. Early on that usually means reducing irritability in the muscle, identifying the movements and positions that are aggravating it, and beginning gentle loading as soon as the tissue can tolerate it. Hip strengthening exercises become a central part of recovery once the acute phase settles, because rebuilding strength through the full range of motion is what allows you to return to activity without re-injury.

Rather than complete rest, the goal is to find what the muscle can currently handle and progress carefully from there. Hip flexor tissue responds well to graded loading, but the timing and approach matter, and going back too fast is one of the most common reasons strains become recurring problems.

Hands-on treatment may help reduce muscle tension and improve hip mobility in the early stages, but the lasting gains come from progressive strengthening and addressing the underlying factors that contributed to the strain. Changes to how you warm up, structure your training, and manage workload often play an important role.

Education matters here more than people expect. Understanding what grade of strain you are dealing with, what a realistic recovery timeline looks like, and how to pace your return to full activity helps you avoid the setbacks that come from doing too much too soon.

Hip Flexor Strain Treatment in Burlington

Getting a hip flexor strain properly assessed and treated usually involves more than rest alone. Depending on the severity and what is driving the problem, care may combine hands-on treatment to reduce muscle irritability and restore hip mobility with a progressive strengthening program to get you back to full function.

Chiropractic Treatment

When tightness or restricted movement at the hip joint or lumbar spine is contributing to how the hip flexor is being loaded, chiropractic treatment may help restore movement through the affected area. Active Release Technique is particularly well suited to muscle strains and can be used to address the hip flexor directly, while Graston Technique may help with any soft tissue restrictions that are slowing recovery.

Massage Therapy

Tension in the hip flexors, quadriceps, and surrounding muscles can maintain pain and limit recovery long after the initial injury. Soft tissue treatment may help reduce that tension and improve hip mobility, and works well alongside acupuncture for managing pain and muscle sensitivity in the early stages of healing.

Physiotherapy

Rebuilding strength through the full range of hip flexion and retraining the movement patterns that contributed to the strain is usually the most important part of a complete recovery. Physiotherapy may include graded loading exercises, sport specific rehabilitation, and for stubborn cases, laser therapy to support tissue healing or shockwave therapy where the tendon attachment is involved.

What to Expect as Your Hip Flexor Heals

Recovery depends on how the muscle responds as pain settles and strength is gradually rebuilt. The process adapts based on the severity of the strain and how your hip tolerates increasing activity over time.

Letting It Settle

Reducing muscle irritability, identifying the movements and activities that are aggravating the hip flexor, and beginning gentle loading as soon as the tissue is ready.

Rebuilding Strength

Progressively loading the hip flexor through its full range to restore muscle strength and endurance, and prepare it for the specific demands of your sport, training, or daily activity.

Doing the Work

Following a structured exercise program between appointments focused on hip strength, movement quality, and the muscle imbalances that contributed to the strain.

Back in Action

Monitoring how the hip responds as training demands increase and making sure you are ready for full activity before returning, so the injury does not come back.

Hip Flexor Strain Questions, Answered

Hip flexor injuries raise a lot of questions, especially around when it is safe to return to activity. Here are the ones that come up most in clinic.

How do I know if I have a hip flexor strain or something else?

Hip flexor strains typically cause pain at the front of the hip or groin that is worse with lifting the knee, stretching the hip back, or activities like running and kicking. The pain is usually localised and provoked by using or stretching the muscle. If your symptoms are more diffuse, refer into the groin or inner thigh, or are not clearly linked to hip flexor movement, it is worth getting a proper assessment to rule out other causes like a groin strain, hip joint problem, or referred pain from the lumbar spine.

Should I rest completely or keep moving?

Complete rest is rarely the best approach. In most cases, gentle movement within a pain-free range helps the muscle heal more effectively than doing nothing. The key is finding what your hip can currently tolerate and progressing from there. Pushing through significant pain is not helpful, but neither is staying completely inactive.

How long does a hip flexor strain take to heal?

It depends on the severity. A mild strain can settle within a few weeks with the right management. A more significant tear can take two to three months or longer, particularly if you are returning to high demand sport. The biggest factor in how long it takes is usually how well the loading and rehabilitation are managed during recovery.

Can I keep training with a hip flexor strain?

In many cases yes, with modifications. High impact activities like sprinting, kicking, and jumping will likely need to be temporarily avoided, but lower intensity exercise is often fine and can actually support recovery. A proper assessment helps identify what you can keep doing and what needs to be dialled back.

Why does my hip flexor strain keep coming back?

Recurring strains are almost always a sign that the muscle was not fully rehabilitated the first time. People often return to activity when the pain has settled but before the muscle has rebuilt the strength and resilience it needs. Addressing the underlying weakness, tightness, and movement patterns that contributed to the original injury is what breaks the cycle.

Do I need imaging for a hip flexor strain?

Not in most cases. A thorough clinical assessment is usually enough to confirm the diagnosis and guide treatment. Imaging may be considered if the injury appears severe, if there is significant bruising or swelling, or if symptoms are not improving as expected and the extent of the tear needs to be clarified.
