Inner thigh pain during a squat is a frequent experience. This discomfort is typically a sign of strain in the muscles responsible for stabilizing your hips and legs during the movement. While the sensation can be alarming, the pain is usually muscle-related and often responds well to temporary training adjustments and specific recovery methods. Understanding the precise source of the pain and the biomechanical factors contributing to it is the first step toward effective relief and prevention.
Identifying the Source of Pain
The inner thigh is home to the hip adductor group, including the adductor longus, adductor brevis, adductor magnus, gracilis, and pectineus. These muscles originate on the pelvis and attach primarily to the femur. Their primary function is to draw the legs toward the body’s midline, a movement known as hip adduction.
During a squat, these adductor muscles are crucial for both movement and stability. As you descend into the squat, the adductors are eccentrically loaded, meaning they are actively lengthening while under tension to control the movement. This deep stretch at the bottom of the squat, especially with a wide stance, makes them vulnerable to microtears or strains. The adductor magnus also acts as a powerful hip extensor when rising from a deep squat, contributing significant force.
Biomechanical Causes of Strain
One of the most common causes of adductor strain during squatting is improper form, particularly when the knees collapse inward. This inward knee motion places excessive and uneven stress on the adductor muscles as they struggle to stabilize the joint against the lateral forces of the weight. The adductors are often forced to compensate for weakness in the larger hip abductor muscles, such as the gluteus medius, which should be controlling the outward tracking of the knees.
Another contributing factor is insufficient hip mobility. When the hip joint capsule or surrounding muscles, like the hip flexors, are tight, the body may shift strain to the inner thigh to achieve depth. Furthermore, poor warm-up routines or a rapid increase in training volume or weight can overload the adductors. Introducing new, heavier loads or significantly increasing the frequency of squatting without adequate preparation stresses the tissues beyond their current capacity, leading to strain.
Immediate Self-Care and Recovery Strategies
For acute inner thigh pain, initial care often involves the R.I.C.E. protocol. Rest is important to prevent further damage and allow the initial healing process to begin. Applying ice to the painful area for 10 to 15 minutes at a time can help reduce local pain and swelling in the first 24 to 48 hours.
While complete rest was once the standard recommendation, current best practices suggest starting gentle, pain-free movement after the acute pain subsides. Low-impact strengthening exercises are often introduced early to facilitate healing and restore function. A highly effective exercise for adductor strengthening is the Copenhagen plank, which is performed by supporting the body on the forearm and the inner thigh of the top leg. This exercise specifically targets the adductors in a stabilizing role, which is crucial for returning to squatting.
Gentle, passive stretching, such as the butterfly stretch, should be performed only after the initial painful phase has passed. These stretches help restore flexibility but should never be forced or taken to the point of sharp pain. It is important to temporarily stop all high-load squatting and activities that reproduce the inner thigh pain. Focus on maintaining overall fitness with pain-free alternatives until you can comfortably perform a bodyweight squat without discomfort.
When to Seek Professional Guidance
While many adductor strains are minor and resolve with self-care, there are specific signs that indicate the need for a consultation with a medical professional, such as a physician or physical therapist. You should seek guidance if you experience a sharp, sudden, or tearing pain accompanied by an audible “pop.” Significant swelling, bruising that appears quickly, or an inability to bear weight on the affected leg are also immediate red flags.
Pain that limits your daily activities or persists and fails to improve after seven to ten days of rest and self-care suggests a more significant injury. A professional can accurately diagnose the issue, rule out other causes of groin pain like a hip impingement or sports hernia, and develop a structured rehabilitation plan. Early intervention is essential to prevent a minor issue from developing into a chronic problem that could affect your long-term movement and training.
