Hip Flexor Pain When Walking, Running, or Climbing Stairs: Causes and Treatment

October 27, 2026

Does the front of your hip hurt when you walk, run, or climb stairs? You might notice a sharp pain when lifting your knee, an uncomfortable pulling sensation in your groin, or an aching feeling that gets worse the longer you’re active.

Hip flexor pain can make even simple activities uncomfortable. And if you’re a runner, hiker, or someone who enjoys staying active, it can be particularly frustrating.

The good news is that many causes of hip flexor pain respond well to conservative treatment, including physical therapy.

At Gordon Physical Therapy in Spokane Valley, WA, we help patients understand why their hip flexors are hurting and develop individualized treatment plans that combine hands-on manual therapy, targeted exercises, and gradual return to activity.

Let’s look at why hip flexor pain often shows up during walking, running, or climbing stairs—and what you can do about it.

What Causes Hip Flexor Pain During Activity?

Your hip flexors are a group of muscles responsible for lifting your thigh toward your body.

Some of the primary hip flexors include:

• Iliopsoas: A powerful hip flexor consisting of the iliacus and psoas muscles.

• Rectus femoris: One of the quadriceps muscles that helps flex the hip and extend the knee.

• Sartorius: A long muscle that assists with several hip and knee movements.

These muscles work repeatedly throughout the day, especially during activities involving walking, running, and climbing stairs.

When the demands placed on these muscles exceed their current capacity—or when a muscle or tendon becomes irritated—you may experience pain in the front of your hip or upper thigh.

However, not all anterior hip pain comes from the hip flexors. Hip joint conditions and other problems can produce similar symptoms.

1. Why Do My Hip Flexors Hurt When Walking?

Walking requires your hip flexors to help bring your leg forward during each step.

If your hip flexors are irritated, even normal walking can become uncomfortable.

Common reasons for hip flexor pain when walking

Overuse or a sudden increase in activity

If you’ve recently started walking longer distances, increased your daily steps, or returned to exercise after a period of inactivity, your hip flexors may not yet be accustomed to the increased workload.

Hip flexor muscle or tendon irritation

A strained muscle or irritated tendon may become painful as it repeatedly contracts during walking.

Reduced hip mobility

Limited hip extension or other mobility restrictions may change how you walk and contribute to discomfort. However, limited mobility doesn’t necessarily mean your hip flexors are simply too tight.

Weakness or reduced endurance

If your hip flexors or surrounding muscles lack sufficient strength or endurance, longer walks may become increasingly uncomfortable.

What if your hip hurts more the longer you walk?

If pain gradually increases during walking, it may indicate that the activity is exceeding your current tolerance.

In some cases, temporarily shortening your walks, reducing hills, or adjusting your pace can help calm symptoms while you work on the underlying problem.

However, persistent pain with walking deserves evaluation, particularly if symptoms are worsening or you’re developing a limp.

2. Why Do My Hip Flexors Hurt When Running?

Running places substantially greater demands on your hip flexors than ordinary walking.

Your hip flexors help move your leg forward during the running cycle, and their workload can increase with speed, hills, and certain training demands.

Common causes of hip flexor pain in runners

Increasing mileage too quickly

A sudden increase in weekly mileage can overload muscles and tendons that haven’t had enough time to adapt.

Hill running

Running uphill generally requires greater hip flexion and may increase the demands on the hip flexor muscles.

Speed workouts and sprinting

Faster running can increase the demands placed on the hip flexors, particularly during rapid leg movement.

Hip flexor weakness or reduced capacity

Sometimes runners focus heavily on stretching their hip flexors without considering whether these muscles have enough strength and endurance for their training demands.

Changes in running mechanics

Stride characteristics, cadence, hip motion, and other running mechanics may influence how forces are distributed during running.

However, there isn’t one perfect running form for everyone, and changes should be based on the individual rather than assuming a particular stride pattern is always harmful.

Should you keep running with hip flexor pain?

It depends on the severity of your symptoms and the likely cause.

Mild discomfort that remains stable and settles quickly afterward may sometimes be managed by modifying your training.

However, pain that progressively worsens, causes limping, or persists after activity shouldn’t be ignored.

Important: Runners who develop deep groin pain, pain with weight-bearing, or pain that worsens with impact may need medical evaluation to rule out a bone stress injury, particularly if they’ve recently increased their training.

Continuing to run through a suspected stress fracture can make the injury worse.

How running analysis may help

At Gordon Physical Therapy, we also offer running analysis to help evaluate movement patterns that may contribute to pain or reduced running efficiency.

Depending on the findings, we may recommend adjustments to training, running mechanics, strength, or mobility.

The goal isn’t to force every runner into the same technique. It’s to identify changes that may be helpful for your specific symptoms and goals.

3. Why Do My Hip Flexors Hurt When Climbing Stairs?

Climbing stairs requires greater hip flexion than level walking.

Every time you step onto a higher stair, you must lift your thigh while coordinating the muscles around your hip, pelvis, and trunk.

If your hip flexors are irritated or lack sufficient capacity, stair climbing may reproduce pain.

Common reasons for hip flexor pain on stairs

• Hip flexor muscle or tendon irritation

• Weakness or reduced endurance

• Increased demands from higher steps

• Hip joint irritation

• Changes in movement patterns due to pain or limited mobility

One useful distinction is whether pain occurs primarily when lifting your leg onto the next step or when pushing your body upward over that leg.

Pain during active leg lifting may raise suspicion for hip flexor involvement, while pain during weight-bearing may prompt closer evaluation of the hip joint and other structures.

However, neither pattern is specific enough to establish a diagnosis by itself.

Is It Really Your Hip Flexor—or Could It Be Your Hip Joint?

This is an important question.

Pain in the front of the hip doesn’t automatically mean you have a hip flexor problem.

Other possible causes include:

• Hip impingement

• Hip labral problems

• Hip osteoarthritis

• Referred pain from the lower back

• Other muscle, tendon, or bone-related conditions

For example, someone with hip joint irritation may experience pain during stair climbing or running that feels very similar to hip flexor pain.

That’s why it’s important to evaluate the hip rather than simply assuming the painful area needs more stretching.

We discuss these differences in more detail in our previous article:

Hip Flexor Pain or Hip Joint Pain? How to Tell the Difference

Why Stretching Your Hip Flexors May Not Solve the Problem

If your hip flexors hurt during walking, running, or stair climbing, your first instinct might be to stretch them.

And sometimes gentle stretching is helpful.

But if the hip flexor muscles or tendons are already irritated, repeatedly stretching them may not address the underlying problem.

In some cases, aggressive stretching can actually increase discomfort.

A muscle that feels tight isn’t necessarily a muscle that needs more stretching.

For example, imagine a runner whose hip flexors become painful after increasing weekly mileage.

The problem may be related to the increased workload rather than a lack of flexibility.

In that situation, modifying training and gradually improving strength and endurance may be more useful than repeatedly performing deep hip flexor stretches.

We explain this concept in greater detail in the first article of our series:

Why Are My Hip Flexors So Tight? Why Stretching May Not Be the Answer

How Physical Therapy Can Help With Hip Flexor Pain

At Gordon Physical Therapy in Spokane Valley, we believe effective treatment starts with identifying why your hip hurts.

We don’t automatically assume that every painful hip flexor needs stretching or that every patient should perform the same exercises.

Instead, we develop an individualized plan based on your symptoms, examination findings, and activity goals.

Step 1: Hands-On Treatment to Help Reduce Pain and Muscle Tightness

One of the things that makes our treatment approach different is our emphasis on hands-on manual therapy, particularly during the early stages of treatment when pain and muscle guarding are limiting movement.

Depending on your examination findings, we may use:

• Soft tissue mobilization to the hip flexors and surrounding muscles

• Hands-on techniques to help reduce muscle pain and guarding

• Hip joint mobilization or traction when appropriate

• Manual therapy for nearby areas, including the lower back or pelvis, when relevant

These techniques may help reduce pain and improve comfortable movement, making it easier to begin an appropriate exercise program.

We generally prefer to address significant pain and irritability before pushing someone into exercises that repeatedly aggravate their symptoms.

However, manual therapy isn’t necessary for every patient and is typically most useful when combined with progressive exercise and activity modification.

Step 2: Improve Hip Strength and Endurance

Once symptoms are more manageable, we focus on improving the muscles’ ability to handle everyday activities.

This may include strengthening:

• Hip flexors

• Gluteal muscles

• Hip stabilizers

• Abdominal and trunk muscles

For some patients, we begin with gentle isometric exercises that activate the muscles without requiring much movement.

As symptoms improve, we can progress toward more challenging strengthening exercises.

The goal is to gradually increase the hip’s capacity to tolerate walking, running, and stair climbing.

Step 3: Restore Comfortable Hip Mobility

If limited hip mobility is contributing to symptoms, we may incorporate appropriate mobility exercises.

However, we don’t automatically prescribe aggressive hip flexor stretching.

Instead, we determine which movements are restricted, which movements reproduce symptoms, and how to improve mobility without unnecessarily irritating the area.

Step 4: Gradually Return to Walking, Running, and Stairs

The final step is helping you return to your normal activities.

For someone who enjoys walking, this might involve gradually increasing distance and reintroducing hills.

For a runner, we may develop a progressive return-to-running program that considers training volume, speed, terrain, and symptom response.

For someone struggling with stairs, we may work on step height, lower-extremity strength, and movement tolerance.

The goal is not simply to make your hip feel better during a treatment session. It’s to help you return to the activities you enjoy without recurring pain.

What Can You Do at Home for Hip Flexor Pain?

If you’re experiencing mild hip flexor pain, a few simple changes may help.

Temporarily reduce aggravating activities

You may need to shorten your walks, avoid steep hills, reduce running mileage, or modify exercises that repeatedly aggravate symptoms.

This doesn’t necessarily mean you need complete rest.

In many cases, maintaining comfortable activity while temporarily reducing excessive demands is preferable to stopping all movement.

Avoid aggressive stretching

If stretching causes sharp pain or leaves your hip feeling worse afterward, don’t continue forcing the movement.

Gentle, comfortable mobility may be appropriate, but more stretching isn’t always better.

Gradually rebuild strength

Strengthening can be helpful when muscle weakness or reduced capacity contributes to symptoms.

However, the right exercises and starting intensity depend on the condition.

If you aren’t sure whether your symptoms are coming from the hip flexors or the hip joint, getting evaluated before starting an aggressive exercise program may be beneficial.

Pay attention to how your hip responds

Consider whether your pain:

• Increases during activity

• Causes you to limp or change your movement

• Persists after exercise

• Feels worse the following morning

• Improves when you temporarily reduce activity

These patterns can help guide activity modifications and provide useful information during a physical therapy evaluation.

When Should You See a Physical Therapist?

An evaluation may be helpful if:

• Your hip hurts whenever you walk, run, or climb stairs

• Pain keeps returning when you resume exercise

• You’ve been stretching without improvement

• You experience painful clicking, catching, or pinching

• You notice weakness or reduced hip mobility

• Symptoms are affecting your normal daily activities

• Pain has persisted for several weeks

Seek prompt medical assessment if you develop severe pain, cannot bear weight, have significant pain after an injury, or experience worsening deep groin pain with impact activity.

Frequently Asked Questions About Hip Flexor Pain

Why does my hip flexor hurt when I lift my leg?

Lifting your leg activates the hip flexor muscles. If a muscle or tendon is irritated, this movement may reproduce pain. However, hip joint problems can also cause pain with leg lifting, so the symptom isn’t specific to one diagnosis.

Can weak hip flexors cause pain when walking?

Reduced hip flexor strength or endurance may contribute to discomfort during walking, particularly when activity demands exceed the muscles’ capacity. However, weakness is only one possible factor, and not all hip flexor pain is caused by weak muscles.

Is walking good for hip flexor pain?

Walking may be helpful if it is comfortable and doesn’t cause progressively worsening symptoms. Some people benefit from temporarily reducing walking distance or avoiding hills while symptoms settle. Others may need further evaluation before continuing weight-bearing activity.

Why does my hip hurt more when walking uphill?

Walking uphill generally requires greater hip flexion and can increase the demands placed on the hip flexor muscles. However, hip joint conditions and other problems can also cause pain with hills.

Should I use heat or ice for hip flexor pain?

Both may provide temporary symptom relief. Ice may be more comfortable after a recent painful injury, while heat may help some people with stiffness or muscle discomfort. Neither replaces an appropriate rehabilitation plan, and the choice can be guided by what feels best and the nature of the condition.

Can physical therapy help hip flexor pain without surgery?

Yes. Many hip flexor muscle and tendon problems improve with conservative treatment, including activity modification, progressive strengthening, mobility exercises, and physical therapy. The treatment approach depends on the underlying diagnosis and severity of symptoms.
