  • Groin
  • Hip
  • Anterior thigh

What This Pain Feels Like

A deep, aching pain in the groin and anterior hip that can be difficult to distinguish from hip joint pathology. The discomfort often radiates into the inner thigh and may feel like a deep pulling sensation originating from within the pelvis. Patients frequently report increased pain during activities involving hip rotation such as pivoting, kicking, or changing direction while running. The pain may also be provoked by prolonged sitting with legs crossed or during sexual activity, and is commonly mistaken for adductor strain or hip joint arthritis.

What Patients Report

  • Hip discomfort
  • Anterior thigh ache

Symptoms patients report

Groin pain Deep inguinal aching from obturator externus trigger points near obturator foramen region

Hip pain Anterior hip joint pain from obturator externus trigger point referral to hip capsule area

Thigh discomfort Anterior thigh aching from obturator externus distal trigger point referral pattern

Deep groin pain Deep groin ache from obturator externus trigger point referral through obturator foramen region

Medial thigh ache Referred medial proximal thigh pain from obturator externus trigger point near trochanteric fossa

Pain with hip adduction Hip adduction loads obturator externus in its secondary role aggravating active trigger points

Deep hip joint sensation Obturator externus trigger point referral mimics intra-articular hip pathology due to deep location

Difficulty with wide-stance activities Wide stance positions stretch obturator externus aggravating trigger points near trochanteric insertion

Common causes

Running Repetitive hip rotation during running gait cumulatively overloads obturator externus fibers

Hip rotation Sustained or forceful hip external rotation overloads obturator externus muscle directly

Sports Activities requiring hip rotation and adduction control overload obturator externus chronically

Overuse Exceeding deep hip rotator recovery capacity creates persistent obturator externus dysfunction

Adductor overuse activities Activities requiring forceful adduction co-activate obturator externus creating secondary overload

Ice skating or skiing Lateral leg movements in skating and skiing cyclically load obturator externus through rotation

Post-hip surgery guarding Protective deep rotator guarding after hip surgery creates sustained obturator externus contraction

Chronic adductor strains Repeated adductor injuries create compensatory obturator externus overload during recovery phases

Horseback riding Sustained adduction and external rotation during riding overloads obturator externus chronically

Treatment & self-care

Professional Treatment

Clinician-guided care for deep groin tenderness

Have the hip and groin examined before targeting this deep muscle. A clinician can select appropriate manual therapy, supported movement or other treatment based on the findings. Avoid pressing deeply into the upper groin crease or searching toward the pubic bone; use the comfortable hip exercises agreed with the clinician between visits.

Duration
A brief assessed treatment trial followed by a movement check
Frequency
Individualized after examination
Expect
Improved comfort with the chosen hip task when treatment matches the assessed cause

Caution Stop contact for a pulse, tingling, numbness or spreading pain. Seek assessment for a painful groin bulge, swelling or increasing difficulty bearing weight.

Immediate Relief

Adductor butterfly stretch

Sit on the floor with the soles of your feet together and knees out to the sides in a butterfly position. Gently press the knees toward the floor using your elbows while keeping your back straight. Hold for 30 seconds. To increase the stretch on the obturator externus, lean your upper body slightly forward from the hips while maintaining a straight spine. You should feel a deep stretch in the inner groin and upper inner thigh.

Duration
30 seconds, 3-4 repetitions
Frequency
3-4 times per day
Expect
Work toward comfortable hip motion; compare the range used in walking or sitting.

Exercises

Side-lying hip adduction with rotation

Lie on your side with the affected leg on the bottom. Bend the top leg and place the foot flat on the floor in front of the bottom knee for stability. Keeping the bottom leg straight, lift it upward toward the ceiling, then slowly rotate the hip so the toes point slightly upward at the top of the movement. Hold for 3 seconds, then lower slowly. This engages the obturator externus through combined adduction and rotation. Progress by adding a light ankle weight.

Duration
3 sets of 12-15 repetitions
Frequency
Every other day
Expect
Build hip strength and control; track walking, stairs or the relevant activity.

Exercises

Seated hip rotation exercise

With feet supported, gently press the knees outward against a light loop band, then return slowly. The band assists the inward return. For a separate inward squeeze, use a soft pillow between the knees. These are regional hip exercises.

Duration
3 sets of 10 repetitions in each direction
Frequency
3 times per week
Expect
Build hip strength and control; track walking, stairs or the relevant activity.

Lifestyle Changes

Activity and posture modifications for hip health

Avoid prolonged sitting with legs crossed, as this places the obturator externus in a shortened, compressed position. During sports, warm up the hip rotators with gentle leg swings and circles before vigorous activity. If you sit at a desk, keep your feet flat on the floor with hips and knees at approximately 90 degrees. Avoid sudden pivoting or twisting movements on a planted foot during recreational activities until the trigger point has resolved.

Duration
Ongoing during daily activities
Frequency
Daily
Expect
Reduce provoked symptoms while maintaining tolerable activity; progress with the response.

Professional Treatment

Professional evaluation for persistent deep groin pain

If deep groin or anterior hip pain persists beyond 4 weeks despite self-care, consult a physiotherapist, sports medicine specialist, or orthopedic surgeon. The obturator externus is a deep, difficult-to-access muscle that may require professional manual therapy, dry needling under ultrasound guidance, or specific rehabilitation protocols. A specialist can rule out hip labral tears, femoral acetabular impingement, sports hernia, or adductor tendinopathy that may present similarly.

Duration
Initial evaluation: 45-60 minutes
Frequency
As recommended, typically 1-2 sessions per week for 4-6 weeks
Expect
A working diagnosis and an individualized treatment plan, with progress judged by the relevant daily activity.

Differential diagnosis

  • Groin strain
  • Hip pathology
  • Hip osteoarthritis
  • Obturator nerve entrapment
  • Adductor strain
  • Hip labral tear
  • Stress fracture (pubic ramus)
