Common Hip Flexor Injuries and Treatments

Updated: June 25, 2025 | By Dr. Steve Hamilton, Board-Certified Orthopedic Specialist

Hip flexor injuries can make everyday movements like walking or lifting your leg painful. Whether you’re an athlete or simply active, understanding these injuries and their treatments can help you recover faster. This guide explains where hip flexor pain is felt, common injuries like strains and tendonitis, and effective at-home treatments. For personalized care, schedule a consultation with Beacon Orthopaedics.

What Are Hip Flexors and Where Is Pain Felt?

Hip flexor muscles (e.g., iliopsoas, rectus femoris) connect your hip joint to your thigh, enabling you to lift your knee or bend at the waist. When injured, pain is typically felt in:

  • Front of the hip or groin (e.g., during walking or climbing stairs)

  • Upper thigh or pelvis

  • Lower back (common with iliopsoas syndrome)

Pain when lifting your leg or climbing stairs? This could indicate a hip flexor strain or tendonitis. Keep reading to learn causes and treatments.

Common Hip Flexor Injuries

1. Hip Flexor Strains

A hip flexor strain happens when these muscles are stretched or torn, often from overuse or sudden movements. Strains are graded by severity:

  • Grade I: Mild stretching with minor pain; hip functions normally.

  • Grade II: Moderate tears causing pain; hip may give out during walking.

  • Grade III: Complete tear; hip cannot bear weight, often requiring medical attention.

Symptoms:

  • Pain in the front of the hip or groin

  • Pain or weakness when lifting the knee or climbing stairs

  • Swelling, bruising, or a limp

  • Muscle spasms or visible deformity (severe cases)

Causes:

  • Overuse (e.g., running, cycling, swimming)

  • Direct trauma (e.g., a fall or impact)

  • Osteoarthritis or poor posture

Tip: Grade I and II strains often heal with rest and stretches. For Grade III or if you can’t bear weight, contact a hip specialist.

2. Hip Flexor Tendonitis

Tendonitis is inflammation of the tendons connecting hip flexor muscles to bones, often caused by repetitive stress.

Symptoms:

  • Gradual pain in the hip, back, or leg

  • Stiffness or swelling

  • Redness or warmth around the tendon

Causes:

  • Overuse (e.g., HIIT workouts, kicking, squatting)

  • Bad posture or walking habits

  • Arthritis (rheumatoid, osteoarthritis, or gout)

Tip: Rest and gentle stretching can help. Persistent pain? Book an evaluation.

3. Iliopsoas Syndrome (Psoas Syndrome)

Iliopsoas syndrome affects the iliopsoas muscles (psoas and iliacus), key hip flexors that support posture and movement. Injury or inflammation here can also affect the nearby iliopsoas bursa.

Symptoms:

  • Pain in the lower back, groin, or thigh

  • Pain when lifting legs or standing from sitting

  • Radiating leg pain or difficulty climbing stairs

Causes:

  • Sudden contraction (e.g., sprinting)

  • Overuse (e.g., running, plyometrics)

  • Rheumatoid arthritis

Tip: Athletes are at higher risk. Early treatment can prevent worsening symptoms.

At-Home Treatments for Hip Flexor Pain

For mild to moderate injuries (Grade I-II strains or tendonitis), try these conservative treatments:

1. RICE Method

  • Rest: Avoid activities that stress the hip. Use crutches if needed.

  • Ice: Apply a cold pack (wrapped in a towel) for 15-20 minutes, 3-4 times daily.

  • Compression: Use an elastic bandage to reduce swelling (not too tight).

  • Elevation: Prop your hip above heart level when lying down.

2. Stretching and Strengthening

Stretching improves flexibility, while strengthening prevents future injuries. Try these exercises (consult a doctor first if pain persists):

  • Seated Butterfly Stretch:

    • Sit with feet together, knees bent outward, back straight.

    • Lean forward until you feel tension; hold for 30 seconds.

  • Lunge Stretch:

    • Step forward, lower hips until knees are at 90 degrees.

    • Squeeze rear glute; hold for 20-30 seconds per side.

  • Forearm Plank:

    • Rest on forearms, keep body straight, hold for 15-30 seconds.

3. Work with a Physical Therapist

Weak hip flexors increase injury risk. A physical therapist at Beacon Orthopaedics can design a sport-specific program for runners, golfers, or swimmers to strengthen your hips and improve performance. Learn about our physical therapy services.

When to See a Hip Specialist

Seek professional care if you experience:

  • Inability to bear weight on the hip

  • Severe swelling or pain that doesn’t improve

  • Decreased range of motion

  • Direct trauma (e.g., a fall or impact)

What causes pain in the front of the hip when lifting the leg?
This is often due to a hip flexor strain or tendonitis, caused by overuse, sudden movements, or weak muscles. Rest and stretching can help mild cases.

Why does my hip hurt when walking up stairs?
Pain during stair climbing may indicate a hip flexor strain or iliopsoas syndrome, triggered by repetitive stress or poor posture.

While a sharp pain in the hip, groin, pelvis, or thigh is an obvious sign of a hip flexor injury, pain in the lower back and leg are easy to misdiagnose. After all, it’s natural to assume that radiating pain in the leg or lower back originate from these areas. Unfortunately, diagnosing the source of a patient’s pain is not always straightforward. In fact, it’s possible for patients to go years with a misdiagnosed injury.

Only a professional orthopaedist can accurately diagnose hip pain and recommend the appropriate treatment. Dr. Steve Hamilton is a board-certified hip specialist at Beacon Orthopaedics and Sports Medicine who can conduct a comprehensive evaluation of your condition and provide an accurate diagnosis.
