Inner thigh pain, often referred to as inner hip pain or groin pain, is a common issue that can affect people of all ages.
Whether it creeps in slowly with daily activity or strikes suddenly after an injury, inner thigh hip pain can really interfere with your movement and quality of life.
It may be a simple issue like a pulled muscle or a sign of something more serious like an infection.
In this guide, we’ll look at the most common causes of inner thigh pain, what symptoms to look out for, how it’s diagnosed, when to see a doctor, and the most effective treatment options. If your pain is more in the front of your hip or thigh check out the following articles: front hip pain and upper thigh pain.
There are a number of possible causes of pain in the inner thigh that all present slightly differently:
A groin strain is one of the most frequent causes of inner hip and groin pain, especially in athletes.
It happens when the adductor muscles (the muscles which bring your legs together) are overstretched or torn. This can happen suddenly during quick movements or gradually from overuse, particularly if you don’t warm up properly or stretch.
Common symptoms of an adductor strain include sharp pain in the inner thigh, especially during side-to-side movement, swelling, bruising and reduced strength in the leg. You may also notice a popping sound at the time of injury.
Femoroacetabular impingement (FAI), aka hip impingement syndrome, is another common cause of inner hip and thigh pain. It occurs when the bones of the hip joint are abnormally shaped with extra bone growth. This causes abnormal contact between the ball and socket of the hip joint resulting in friction and irritation. This can lead to cartilage damage and cause inner hip pain.
There are three types of impingement, Cam, Pincer and Mixed depending on where the bone growth is.
Common symptoms of hip impingement syndrome include a deep aching hip and groin pain, sharp inner hip thigh with leg movements, reduced range of motion and occasional clicking or locking. Symptoms often worsen with activities that involve hip rotation or flexion.

Osteoarthritis or inflammatory arthritis in the hip is a common cause of hip and inner thigh pain in older adults. As the cartilage wears down or inflammation builds up, the joint becomes stiff, swollen, and painful.
Common symptoms of hip arthritis include a dull ache in the groin or thigh, stiffness in the morning or after rest, pain that worsens with activity, grinding or creaking sounds with movement and weakness in the leg.
Hip osteoarthritis is most common in people over the age of 60, or those with a history of joint overuse or previous hip injuries.
Another possible cause of inner hip and thigh pain is a hip labral tear.
The labrum is a ring of cartilage that surrounds the hip socket, to improve its stability and provide cushioning. Tears in the labrum can lead to instability and pain in the inner thigh.
Hip labral tears are usually caused by sudden impact e.g. a fall, repetitive overuse e.g. pivoting movements in sport, hip impingement or gradual degeneration.
Common symptoms of hip labral tears include clicking, catching or locking of the hip, pain with rotation or twisting, inner thigh or groin discomfort and reduced hip mobility. Pain can be sharp or deep or persistent.

Inner thigh pain that is accompanied by a lump in or around the groin often indicates a hernia. Hernias occur when internal tissue pushes through a weak spot in the abdominal wall.
The most common type that causes inner hip and thigh pain is an Inguinal Hernia, where part of the intestine or fatty tissue protrudes through the inguinal canal in the groin. It often presents as a bulge that increases in size when straining or coughing and may cause a burning or aching sensation in the groin area.
Nerve compression either in the lower back or front of the pelvis can cause referred pain into the inner thigh. Common culprits include lumbar disc herniation, spinal stenosis, or entrapment of the obturator or femoral nerve.
Common symptoms of inner thigh pain from nerve issues are burning, tingling, or shooting pain in the inner hip and thigh, numbness, pins and needles, and sometimes weakness. Symptoms often worsen with standing or walking.
Another possible nerve problem is Meralgia Paresthetica, which usually causes outer thigh symptoms, but in rare cases can affect the inner thigh due to nerve variation.
Common during pregnancy, SPD happens when the ligaments of the pelvic joint become too relaxed allowing the pelvis to move unevenly.
Typical symptoms of symphysis pubis dysfunction include burning or shooting pain in the inner thigh, groin, and pelvis, especially when walking, getting in/out of a car, or rolling over in bed. A clicking or grinding feeling in the pelvic region is also common.
SPD is usually associated with hormonal changes, increased joint laxity, and postural alterations during pregnancy, and typically starts during the second trimester. Wearing a pelvic support belt can really help reduce hip and inner thigh pain and instability from SPD.
There are some other less common causes of pain in the inner hip and thigh:
The type and severity of symptoms associated with inner hip and thigh pain vary depending on the underlying cause, but often include:
Diagnosing the cause of pain in the inner thigh, hip or groin usually involves a detailed physical exam and medical history. Depending on your symptoms, your doctor may order:
See your regular doctor if you have:
Seek urgent medical attention if you have:
Inner hip pain treatment depends on the root cause, but common options include:
Inner thigh pain can come from many different sources, ranging from strained muscles and irritated joints to deeper issues like nerve compression or pelvic dysfunction. It is important to identify the underlying cause to get the right treatment.
If you're dealing with inner thigh pain, inner hip pain, or general hip and groin pain, don’t ignore it. The sooner you get to the root of the problem, the faster you can get back to moving comfortably again.
