Each case is unique, so it is recommended to consult a qualified doctor or physiotherapist for an accurate diagnosis and the development of an individualized treatment plan.
Groin Pain
Groin pain is a common musculoskeletal issue that occurs in the inguinal region, where the lower abdomen meets the inner thigh. This pain can be localized or radiate to the hip, lower back, or even the knee, depending on the underlying cause. It may present as sharp and sudden, often seen in acute sports injuries, or chronic and persistent, usually linked to joint dysfunctions, nerve entrapments, or repetitive strain injuries.
Anatomy and Biomechanics
The groin area is a structurally complex region consisting of muscles, tendons, ligaments, nerves, blood vessels, and joints, all of which contribute to hip and pelvic stability. Pain in this area is often caused by imbalances, injuries, or degenerative conditions affecting these structures.
Key anatomical structures involved in groin pain:
- Adductor muscles: The adductor longus, adductor brevis, adductor magnus, gracilis, and pectineus are responsible for bringing the thigh inward. Overuse or acute injuries can cause adductor strain or tendinopathy.
- Iliopsoas muscle: A deep hip flexor that plays a crucial role in hip movement and posture. Overuse or tightness can lead to iliopsoas bursitis or hip impingement, causing groin discomfort.
- Hip joint and labrum: The acetabulum and femoral head form the hip joint, and damage to the labrum (cartilage) can result in hip labral tears, which often cause deep groin pain.
- Inguinal ligament and canal: A weak point in the abdominal wall, susceptible to inguinal hernias, where abdominal contents push through the inguinal canal, causing a lump and discomfort in the groin area.
- Nerves and blood vessels: The obturator and femoral nerves run through the groin and can become compressed, leading to neuropathic pain, tingling, or numbness in the inner thigh.
Biomechanically, the groin area is a transition zone between the upper and lower body, meaning it absorbs a significant amount of force during running, cutting, and pivoting movements. Weak core muscles, hip instability, or poor movement mechanics can contribute to chronic groin pain and recurrent injuries.
Incidence
Groin pain is particularly common in athletes, especially those involved in soccer, hockey, rugby, martial arts, and running. Studies show that 10-18% of all sports-related injuries affect the groin, with adductor strains being among the most frequent issues in professional athletes.
Beyond sports-related injuries, groin pain is also common in:
- Middle-aged and older adults with hip osteoarthritis or degenerative joint disease.
- Pregnant women, due to pelvic instability and hormonal changes affecting ligament elasticity.
- Individuals recovering from surgery, particularly hernia repair or hip replacement.
- Patients with nerve entrapments or vascular disorders affecting blood circulation to the lower extremities.
Due to the complex nature of groin pain, early diagnosis and a tailored treatment plan are critical for effective recovery and injury prevention.
Risk Factors
Sports and High-Impact Activities
Athletes participating in high-intensity sports with rapid acceleration, deceleration, and directional changes are at greater risk for groin injuries. Repetitive sprinting, kicking, and pivoting movements can lead to muscle strains, tendon overuse injuries, or hip impingement syndromes.
Muscle Imbalances and Weak Core Stability
A weak core and hip stabilizers increase the stress placed on the groin and adductor muscles, leading to a higher risk of overuse injuries. Research shows that athletes with weak hip abductors are up to three times more likely to experience groin injuries.
Hip Joint Disorders
Underlying hip conditions, such as femoroacetabular impingement (FAI), labral tears, or osteoarthritis, contribute to chronic groin pain by affecting joint mobility, stability, and load distribution. FAI is more prevalent in young athletes, whereas hip osteoarthritis is more common in older individuals.
Previous Groin Injuries
A history of groin strains, adductor tears, or hernias significantly increases the risk of recurrent groin pain. Incomplete rehabilitation or a premature return to activity may cause scar tissue formation and movement compensations, leading to chronic dysfunction.
Poor Posture and Movement Mechanics
Altered hip alignment, pelvic asymmetry, and excessive lumbar lordosis can lead to excessive stress on the groin region, resulting in pain and restricted mobility.
Symptoms
Groin pain symptoms vary depending on the cause, severity, and affected structures. Common symptoms include:
- Localized Pain and Tenderness: Sharp, aching, or burning discomfort in the groin, inner thigh, or lower abdomen. Pain intensity may increase with physical activity, prolonged standing, or sudden movements.
- Radiating Pain: Some groin injuries, such as nerve entrapments or hip joint dysfunctions, cause pain that spreads to the lower back, buttocks, or knee, often resulting in stiffness and mobility restrictions.
- Swelling or Visible Bulging: Inguinal hernias or muscle tears may present with a noticeable lump or swelling, which becomes more prominent with coughing, sneezing, or lifting heavy objects.
- Muscle Weakness or Instability: Adductor or iliopsoas injuries can lead to reduced strength and instability, making activities such as running, squatting, or quick direction changes difficult.
- Clicking or Locking Sensation: Patients with hip labral tears or femoroacetabular impingement (FAI) may experience catching, clicking, or locking sensations in the hip, particularly during rotation or prolonged sitting.
- Numbness, Tingling, or Burning Sensation: Nerve entrapments, such as obturator nerve compression or femoral nerve irritation, can cause altered sensation, tingling, or burning pain in the groin and inner thigh.
Identifying the precise location and nature of the pain is crucial for accurate diagnosis and effective treatment planning.
Diagnosis
Accurately diagnosing groin pain requires a comprehensive clinical evaluation that includes a detailed patient history, physical examination, and imaging studies. Given the complex anatomy of the groin region, a systematic diagnostic approach is essential to distinguish between muscle strains, joint pathologies, nerve entrapments, and referred pain from other areas.
Clinical History and Patient Interview
A thorough patient history is the first step in diagnosing groin pain. A healthcare provider will ask about:
- Onset and duration – Was the pain sudden or gradual? Did it occur after a specific activity or movement?
- Pain characteristics – Is the pain sharp, dull, burning, or radiating? Does it worsen with movement or remain constant?
- Activity level – Are there repetitive movements, high-impact activities, or sports involvement that could contribute to the pain?
- Previous injuries – Have there been past groin strains, hip injuries, or lower back issues that could be linked to the current pain?
- Other symptoms – Any numbness, tingling, swelling, or instability that might suggest nerve involvement, hernia, or joint dysfunction.
Physical Examination
A structured physical examination is crucial to identify pain sources and movement limitations. This typically includes:
- Palpation – The clinician will press on different structures to pinpoint tenderness and inflammation.
- Range of Motion (ROM) Testing – Hip and pelvic mobility are assessed in flexion, extension, abduction, adduction, and rotation. Limited ROM may indicate hip joint pathology, labral tears, or femoroacetabular impingement (FAI).
- Strength Testing – Weakness in hip flexors, adductors, or gluteal muscles may contribute to groin pain.
- Special Tests – Specific maneuvers can help differentiate between muscle, joint, and nerve-related causes:
- FABER Test – Identifies hip joint pathology or sacroiliac dysfunction.
- FADIR Test – Assesses for femoroacetabular impingement (FAI).
- Adductor Squeeze Test – Detects adductor muscle strains or tendinopathy.
- Hernia Examination – Palpation of the inguinal canal to check for bulging or tenderness, indicating a possible hernia.
Imaging Studies
When a clinical examination is inconclusive or severe symptoms persist, imaging studies can provide further insight:
- X-rays – Useful for detecting hip osteoarthritis, femoroacetabular impingement (FAI), or fractures.
- Ultrasound – Helps assess muscle strains, tendon injuries, and hernias in real time.
- MRI – Provides detailed images of soft tissue structures, including hip labrum tears, ligament damage, and chronic muscle injuries.
- CT Scan – Occasionally used for complex bony abnormalities or pelvic fractures.
A combination of clinical assessment and imaging is often necessary to determine the exact cause of groin pain and develop an effective treatment plan.
Treatment and Prevention
Managing groin pain requires a multifaceted approach, incorporating pain relief, rehabilitation, strengthening, and long-term prevention strategies. Treatment should be tailored to the underlying cause, whether it be a muscle strain, hip joint pathology, or nerve irritation.
Conservative Treatment Approaches
Rest and Activity Modification
Reducing physical strain on the affected area is the first step in recovery. Athletes should temporarily avoid high-impact activities such as sprinting, cutting, and jumping to allow the injured tissues to heal. However, complete rest should be avoided, as prolonged inactivity may lead to muscle deconditioning and joint stiffness (Physioworks, 2024).
Pain Management
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can help reduce inflammation and alleviate pain in acute phases. For chronic conditions, manual therapy, dry needling, or corticosteroid injections may be considered in persistent cases (Chelmsford Physiotherapy, 2024).
Physiotherapy and Rehabilitation
A structured physiotherapy program is crucial for regaining mobility, strength, and function. Rehabilitation should be progressive and targeted at the underlying dysfunction. Key components include:
- Soft Tissue Mobilization – Manual therapy techniques, such as deep tissue massage and myofascial release, help reduce muscle tension and improve circulation.
- Strengthening Exercises – Focus on core stability, hip adductors, gluteal muscles, and deep abdominal activation to restore functional strength.
- Neuromuscular Re-education – Training in proper movement mechanics to prevent re-injury and improve biomechanics (PMC Physiotherapy, 2024).
Surgery for Severe Cases
If conservative treatments fail or the pain is caused by hip labral tears, femoroacetabular impingement (FAI), or recurrent hernias, surgical intervention may be necessary. Common procedures include:
- Hip Arthroscopy – Used to repair labral tears or remove bony abnormalities in FAI.
- Hernia Repair Surgery – Required for inguinal or femoral hernias causing significant discomfort.
- Adductor Tenotomy – A surgical release of tight or damaged adductor tendons in chronic cases.
Preventing Groin Pain
Preventative strategies are essential, especially for athletes and individuals prone to recurring groin injuries.
Strength and Conditioning
A well-structured strengthening program focused on core, hip stabilizers, and pelvic control can significantly reduce the risk of groin injuries. Exercises should include:
- Adductor strengthening (e.g., Copenhagen planks, side lunges).
- Hip mobility drills (e.g., dynamic stretching, hip openers).
- Core activation (e.g., dead bug exercises, anti-rotation holds).
Proper Warm-Up and Flexibility
A dynamic warm-up routine incorporating gradual intensity increases, active stretching, and movement prep drills reduces muscle stiffness and improves blood flow before physical activity. Studies suggest that athletes with inadequate warm-ups are at a higher risk of groin injuries (Chelmsford Physiotherapy, 2024).
Load Management and Recovery
Monitoring training load and recovery periods is essential in preventing overuse injuries. Gradual progression in intensity and volume, combined with adequate rest periods, minimizes muscle fatigue and strain.
Correcting Movement Mechanics
Addressing poor posture, muscle imbalances, or dysfunctional movement patterns through biomechanical assessments and gait analysis can prevent repetitive strain injuries.
By implementing evidence-based treatment protocols and preventative strategies, individuals suffering from groin pain can recover effectively and reduce the risk of future injuries.
Physiotherapy and Groin Pain
Physiotherapy may help reduce groin pain and improve mobility by addressing muscle imbalances, joint stiffness, and poor movement mechanics. A structured rehabilitation program may include manual therapy, targeted exercises, and movement retraining, depending on the underlying cause of the pain.
Manual Therapy Techniques
Physiotherapists may use manual therapy techniques to release tight muscles, improve joint mobility, and reduce soft tissue restrictions. Some approaches that may help include:
- Soft tissue release – Focuses on relaxing tight adductor muscles and improving flexibility.
- Joint mobilization – Techniques that may help restore hip mobility and reduce joint stiffness.
- Myofascial release – Targets tight fascia and connective tissue, which can contribute to restricted movement and pain.
Strengthening Exercises
A progressive strengthening program is often recommended to improve hip stability, core control, and adductor muscle endurance. Some exercises that may help include:
Isometric Adductor Squeeze
- How to perform:
- Lie on your back with knees bent and feet flat on the floor.
- Place a small ball or pillow between your knees.
- Gently squeeze the ball for 5-10 seconds, then relax.
- Repeat for 3 sets of 10 repetitions.
- Why it may help: May activate and strengthen the adductor muscles, reducing strain on the groin.
Copenhagen Side Plank
- How to perform:
- Lie on your side with your top leg resting on a bench.
- Lift your hips off the ground, supporting your weight on your forearm and top leg.
- Hold for 10-30 seconds, then switch sides.

- Hold for 20-30 seconds, then switch sides.
- Repeat for 3 sets per side.
- Why it may help: May relieve tightness in the hip flexors, which can contribute to groin discomfort.
How Can I Help Myself?
Self-care strategies may support recovery and help reduce discomfort. While these approaches do not replace professional treatment, they may aid in pain management and mobility improvement.
Rest and Load Management
- Avoiding high-impact activities, sudden direction changes, or excessive stretching may help reduce irritation in the groin region.
- Gradually returning to activity rather than making sudden increases in intensity may prevent further strain.
Cold and Heat Therapy
- Applying ice to the painful area for 15-20 minutes at a time may help reduce inflammation in acute injuries.
- Using heat therapy for chronic stiffness may promote blood circulation and muscle relaxation.
Supportive Bracing or Compression
- Compression shorts or groin supports may help stabilize the area and provide additional support during movement.
Maintaining Good Posture and Movement Mechanics
- Correcting pelvic alignment and improving hip mobility may help distribute forces more evenly and reduce strain on the groin muscles.
- Avoiding excessive arching of the lower back may help minimize compensatory stress on the hip joint.
For further guidance, consult with a healthcare professional to determine the best self-management strategies for your condition.
