Groin pain triggered by lifting your leg usually traces back to a muscle strain, tendon irritation, or a problem inside the hip joint itself. The motion of raising your thigh loads a specific chain of structures, from the adductor muscles on the inner thigh to the iliopsoas tendon running deep through the pelvis to the labrum lining the hip socket, and a problem at any point along that chain can produce pain right at the crease of the groin. Because so many structures overlap in a small area, pinpointing the source often takes more than a quick self-assessment, but the pattern of your pain and the specific movements that provoke it can narrow things down considerably.
Adductor Strains and Inner-Thigh Muscle Injuries
The most common muscular cause of groin pain during leg-lifting is a strain of the adductor muscles, particularly the adductor longus. These muscles run from the pubic bone down the inner thigh, and they work hard whenever you bring your leg inward or stabilize your pelvis during single-leg movements. A strain happens when the muscle fibers are stretched or torn beyond their capacity, often during a sudden push-off, a change of direction, or a kick. You’ll typically feel a sharp pain on the inside of the groin that flares when you squeeze your knees together or lift your leg to the side.
Adductor strains are especially prevalent in sports involving lateral movement. Data across 25 college sports found an overall rate of about 1.3 adductor injuries per 1,000 athletic exposures, with men’s soccer and men’s hockey seeing rates roughly two to three times higher than that average. Recurrence is a real issue: roughly one in five professional soccer players and about one in four professional hockey players who strain an adductor will do it again.1PubMed Central. Adductor Strains in Athletes That high re-injury rate is one reason rehabilitation programs emphasize progressive strengthening rather than just resting until the pain fades.
Iliopsoas Tendinopathy and Deep Anterior Pain
If the pain feels deep in the front of the groin rather than along the inner thigh, the iliopsoas may be the culprit. The iliopsoas is the primary hip flexor, the muscle that does the heavy lifting when you raise your knee toward your chest. Its tendon passes over the front of the hip joint, and when it becomes irritated or inflamed, lifting the leg against resistance or climbing stairs can reproduce a dull, aching pain right at the hip crease. Unlike adductor strains, which tend to start with a distinct injury moment, iliopsoas tendinopathy often creeps in gradually from repetitive overuse.
Diagnosing it clinically can be tricky because several other structures sit nearby. Researchers have found that certain physical tests reliably reproduce the pain: resisted hip flexion while seated and a straight-leg raise in external rotation both showed significant pain reduction after a diagnostic injection confirmed the tendon was the source.2PubMed Central. Evaluation of Clinical Tests to Diagnose Iliopsoas Tendinopathy If your pain is worst when you try to lift a straight leg while lying on your back, or when you drive your knee up against your own hand, the iliopsoas tendon is high on the list of suspects.
Snapping Hip Syndrome
Some people notice not just pain but an audible or palpable snap when they lift or rotate their leg. Internal snapping hip occurs when the iliopsoas tendon catches as it slides over the bony ridge at the front of the pelvis. The classic trigger is bringing the hip from a bent, outwardly rotated position into extension with inward rotation. The snap can be loud enough to hear across a room, and some people describe it more as a deep clunk than a click.3Operative Techniques in Sports Medicine. Snapping hip
A painless snap by itself is usually harmless and common in dancers, gymnasts, and runners. When it becomes painful, though, it generally means the tendon or its surrounding bursa has become inflamed. Treatment overlaps with iliopsoas tendinopathy: activity modification, targeted stretching, and strengthening of the hip stabilizers. If conservative care fails, guided injections or, in rare cases, surgical tendon release may be considered.4JBJS Reviews.

Labral Tears and Femoroacetabular Impingement
The hip labrum is a ring of cartilage that lines the edge of the hip socket, helping to seal and stabilize the joint. When it tears, the hallmark symptom is anterior hip or groin pain, sometimes accompanied by a catching or locking sensation during movement.5PubMed Central. A comprehensive review of hip labral tears Lifting the leg, especially with rotation, can pinch the torn tissue between the ball and socket and reproduce a sharp, sometimes stabbing pain deep in the joint.
Labral tears frequently coexist with femoroacetabular impingement, a condition where the shape of the ball or socket creates abnormal contact during hip motion. FAI comes in two forms: one where extra bone on the femoral head jams into the socket rim during flexion, and another where the socket itself is too deep or angled, over-covering the ball. Either pattern increases stress on the labrum during everyday movements like squatting, crossing your legs, or lifting your knee high. An 18-year-old athlete treated for an acute labral tear, for instance, still had muscle imbalances and pain at end-range hip motions even after an intra-articular injection reduced her initial symptoms, highlighting how the structural problem and the surrounding muscular dysfunction feed each other.6PubMed. Management of a Patient With Acute Acetabular Labral Tear and Femoral Acetabular Impingement With Intra-articular Steroid Injection and a Neuromotor Training Program
A combination of physical examination maneuvers can be quite effective at identifying labral tears. When tests that flex, rotate, and load the hip in different directions are all positive together, their sensitivity for detecting a tear is high, sometimes outperforming imaging alone in patients being considered for arthroscopy.7PubMed.

The “Sports Hernia” and Abdominal Wall Weakness
Groin pain that worsens with exertion, coughing, or sit-ups, and that centers near the lower abdomen rather than deep in the hip, may point to a problem in the inguinal region. The term “sports hernia” has been widely used, but researchers and clinicians have long debated what it actually means. Unlike a traditional inguinal hernia, where tissue visibly bulges through a gap in the abdominal wall, a sports hernia involves a weakening or partial tear of the tissues around the inguinal canal without an obvious bulge.8PubMed Central. Sportsman’s hernia? An ambiguous term The terminology is messy enough that many experts now prefer phrases like “inguinal-related groin pain” or “athletic pubalgia” to avoid confusion.
What matters practically is that this kind of pain tends to build over weeks, often on one side, and gets worse with twisting, sprinting, or any movement that loads the lower abdominal wall. Lifting the leg can provoke it because the rectus abdominis and the adductor longus share an attachment at the pubic bone, meaning tension on one structure tugs on the other. Initial treatment is conservative, focusing on core and hip strengthening. If that fails after several months, surgical repair of the weakened tissue has good outcomes in most athletes, though recovery timelines vary.
Bone and Stress-Related Causes
Not all groin pain when lifting the leg comes from soft tissue. Stress fractures of the femoral neck or pubic ramus can produce groin pain that initially mimics a muscle strain but worsens progressively, especially with weight-bearing activity. The tricky part is that early-stage stress fractures, osteonecrosis of the femoral head, and subchondral insufficiency fractures all frequently present with groin pain and unremarkable plain X-rays, making them easy to miss without advanced imaging.9PubMed Central. Optimizing diagnosis and management of ONFH, FNSF, and SIF
These conditions are less common in young, healthy adults than muscle strains or labral tears, but certain populations carry higher risk. Distance runners, military recruits, and anyone who has recently ramped up training volume are more susceptible to femoral neck stress fractures. Osteonecrosis is associated with corticosteroid use, heavy alcohol consumption, and certain blood disorders. If your groin pain came on without a clear injury, aches at rest, or wakes you at night, these diagnoses deserve consideration. An MRI is typically needed to catch them early.
Nerve Entrapment
Groin pain can also have a neuropathic component, meaning the pain originates from a compressed or irritated nerve rather than a damaged muscle or joint. The ilioinguinal and iliohypogastric nerves run through the inguinal canal and can become trapped by overlying tissue, particularly in athletes. In one study analyzing surgical findings in athletes with inguinal-related groin pain, evidence of ilioinguinal nerve compression was found in over 96% of cases, and iliohypogastric nerve compression in over 92%.10PubMed Central. Neuropathic causes of groin pain in athletes: understanding nerve involvement
Nerve-related groin pain often feels different from a muscle strain. Some people report electric or burning sensations that come on suddenly during explosive movements like sprinting or kicking, rather than the constant dull ache of a tendinopathy or the sharp catch of a labral tear. Others feel little during activity but notice tingling or numbness in the groin or inner thigh afterward. These patterns are a clue that a nerve evaluation should be part of the workup, especially if standard muscle and joint treatments haven’t helped.
Adolescent-Specific Concerns
In teenagers, the growth plates around the pelvis and proximal femur haven’t fully fused yet, and those open growth plates are structurally weaker than the surrounding bone and tendons. A sudden violent contraction of the hip flexor, such as during a sprint start or an explosive kick, can pull a piece of bone away from its attachment point. Avulsion fractures of the lesser trochanter, where the iliopsoas tendon yanks off a chip of bone, present with groin pain and a limp, and they typically occur in athletic adolescents.11PubMed Central. Isolated Avulsion Fractures of Lesser Trochanter in Adolescents – A Case Series and Brief Literature Review
Other adolescent conditions that can cause groin pain include Legg-Calvé-Perthes disease, which involves the blood supply to the femoral head, and slipped capital femoral epiphysis, where the growth plate at the top of the femur shifts out of position. Both can present as a vague groin ache that a teenager or parent might attribute to a pulled muscle. Any persistent groin pain in a young person that doesn’t resolve with a few days of rest warrants imaging, because missing these diagnoses can lead to long-term joint damage.
Referred Pain From Outside the Hip
The groin is a crossroads of referred pain. Problems that originate nowhere near the hip can project pain into the groin region, making diagnosis confusing. Lumbar spine issues, particularly disc herniations or nerve root irritation at the upper lumbar levels, can send pain down into the groin. Kidney stones passing through the ureter are a classic source of severe, sudden-onset groin pain. In women, endometriosis and other gynecological conditions can contribute to chronic pelvic pain that overlaps with the groin area; the sustained muscular contraction triggered by altered internal stimuli can create secondary damage to muscles and joints in the pelvic region, blurring the line between a gynecological and a musculoskeletal problem.12PubMed. Musculoskeletal evaluation of the lower pelvic complex in women with endometriosis: A case-control study
The practical takeaway is that if your groin pain when lifting your leg doesn’t fit neatly into a muscle or joint pattern, or if it’s accompanied by urinary symptoms, menstrual changes, or back pain radiating into the leg, the source may not be in the hip at all. A clinician who considers the full picture, not just the hip, will save you time and misdiagnosis.
Getting a Diagnosis
Because so many structures can produce groin pain, a thorough physical examination is the essential first step. A skilled examiner will test resisted hip flexion, adduction strength, hip rotation, and specific provocation maneuvers for the labrum and iliopsoas. The combination of these tests often narrows the diagnosis more effectively than jumping straight to imaging.
When imaging is needed, MRI is the workhorse for groin pain. It can visualize soft tissue injuries like adductor tears and labral damage, bone marrow edema from stress fractures, and structural abnormalities like FAI, all in one scan. It is particularly valuable when pain is poorly localized and multiple structures might be involved. Ultrasound is useful in specific situations, especially for dynamic assessment of the pubic region and for guiding injections, since it allows real-time visualization of movement and needle placement.13PubMed Central. Imaging of Groin Pain: Magnetic Resonance and Ultrasound Imaging Features Plain X-rays are typically a starting point to rule out fractures and check bone morphology, but as noted earlier, they miss many conditions in their early stages.
Conservative Treatment
Regardless of the specific cause, the initial treatment for most groin pain when lifting the leg is conservative: relative rest from aggravating activities, anti-inflammatory measures, and a structured rehabilitation program. The evidence consistently favors active rehabilitation, particularly strengthening, over passive treatments like stretching alone, massage, or electrical stimulation.
A Cochrane review comparing exercise therapy to conventional physiotherapy for exercise-related groin pain found a striking difference. In one trial, about three-quarters of athletes treated with a strengthening-focused program were successfully treated at 16 weeks, compared with less than a third of those given conventional physiotherapy that relied on stretching, electrotherapy, and friction massage. Even more telling, nearly 80% of the strengthening group returned to sport at the same level, compared with only about 13% of the conventional group.14Cochrane Database of Systematic Reviews. Conservative interventions for treating exercise-related groin pain The broader literature echoes this: progressive strengthening of the hip and abdominal muscles, moving from static holds to functional movements, forms the backbone of effective groin pain rehabilitation.15PubMed Central. A systematic review of the literature on the effectiveness of exercise therapy for groin pain in athletes
For longstanding adductor-related groin pain specifically, a systematic review found that manual therapy combined with strengthening exercise and compression clothing therapy had the strongest evidence base among conservative options.16PubMed Central. The conservative treatment of longstanding adductor-related groin pain syndrome: a critical and systematic review One case report documented an athlete returning to sport pain-free after ten weeks of an individualized multimodal program.17PubMed. Pubic and adductor related groin pain in an athlete: A case report linking pathology to conservative care Ten weeks is a reasonable ballpark for many moderate groin injuries, though mild strains resolve faster and more severe tears take longer.
When Conservative Care Is Not Enough
If several weeks of structured rehab haven’t improved things, image-guided injections are a common next step. For iliopsoas-related pain, ultrasound-guided injections of local anesthetic with or without a corticosteroid into the area around the tendon can serve a dual purpose: they confirm the diagnosis if the pain goes away temporarily, and they provide enough relief to let you progress through physical therapy. A systematic review found that iliopsoas injections improved pain scores substantially, from an average of about 7 out of 10 before injection down to about 2.5 after, with low complication rates.4JBJS Reviews. Iliopsoas Injections: A Systematic Review of Patient Outcomes and Progression to Surgery For cases driven by bursitis or tendinopathy after hip replacement, injection results tend to be better than for idiopathic cases, where some patients eventually need surgical tendon release.18PubMed. Diagnostic and therapeutic use of sonography-guided iliopsoas peritendinous injections
For labral tears associated with FAI, surgery typically involves hip arthroscopy to repair the labrum and reshape the bone causing the impingement. This is generally reserved for people who have tried at least three to six months of conservative management without adequate improvement and whose imaging and exam findings match. For sports hernias or athletic pubalgia that don’t respond to core strengthening, surgical reinforcement of the inguinal floor has good return-to-play rates, though it carries the recovery timeline of any abdominal wall surgery.
Returning to Activity and Preventing Recurrence
Coming back too quickly from a groin injury is one of the biggest drivers of re-injury. For adductor strains, a prospective study of male athletes found that those with mild to moderate tears were typically pain-free after about two weeks and returned to full team training around three weeks. More severe grade 3 tears took up to three months. Critically, athletes who met pain-free criteria before returning had fewer reinjuries than those who pushed through.19PubMed Central. Return to Sport After Criteria-Based Rehabilitation of Acute Adductor Injuries in Male Athletes: A Prospective Cohort Study
An expert consensus among professional soccer medical staff validated a set of return-to-play criteria for adductor injuries that goes well beyond “does it still hurt.” The validated criteria include palpation tenderness, hip flexibility, strength testing, quality of movement during sport-specific drills, and performance under simulated match conditions.20PubMed Central. Consensus of Return-to-Play Criteria After Adductor Longus Injury in Professional Soccer You don’t need to be a professional athlete to apply this logic. Before returning to running, lifting, or sport, you should be able to squeeze your legs together against resistance without pain, perform single-leg squats without compensating, and tolerate the specific movements your activity demands at full intensity.
Prevention of recurrence comes down to maintaining hip and core strength after you’ve recovered, not just during rehab. The adductor muscles in particular weaken quickly during a period of rest, and strength imbalances between the adductors and abductors are one of the strongest risk factors for future groin injuries. A simple routine of side-lying hip adduction, Copenhagen planks, and progressive single-leg work, done two to three times per week as part of your regular training, can go a long way toward keeping the problem from coming back.
