Main Causes of Pain in the Hip, Thigh, and Groin

Hip, Thigh, and Groin Pain

What Causes Hip Thigh and Groin Pain?

A recent study of professional soccer players found 20% of all their injuries involved the areas near the thigh or groin. This finding proved the theory that athletes in sports requiring quick footwork, such as soccer or lacrosse, tend to suffer from injury to the hips and groin. This injury often happens because of overuse. The pain associated with hip and groin injuries can be quite severe, so it is important to diagnose the problem to obtain the correct treatment. There are many possible causes of hip and groin pain.

Strained Muscles

One common cause of hip and groin pain is a strain or tear of one or several muscles. Strains often occur due to overuse. A strain often occurs in these following areas:

  • In the hip flexors near the anterior groin area
  • In the muscles found in the inner groin
  • In hip flexors that run along the anterior groin
  • In the fascia on the outside of the hip

The last item on the list is called IT band syndrome, and this is caused by overuse of connective tissues. There is currently no exact way to diagnose this kind of injury. However, a strain can be detected through a trial-and-error method of asking the patient to contract each muscle while pushing against resistance. This method, along with imaging, is one of the best ways to determine the cause of pain.

Labral Tear

Pain that is joint-related often occurs along the crease of the hip or in the groin line. The labrum refers to the circle of cartilage that surrounds the hip joint. A tear in this cartilage can lead the death of bone tissue. If an individual has been treated with steroidal medications, this condition should be considered when diagnosing the cause pain in the hip or groin. A combination of a thorough physical examination and x-rays can often effectively diagnose most causes of pain in the hip region, but in the case of a labral tear, a doctor may order an MRI arthrogram to study the affected area. Dye will be injected directly into this joint before imaging begins.

Stress Fracture

Whenever a patient complains of persistent discomfort in the groin or hip area, a healthcare professional could guess that there may be a stress fracture at the source of the pain. Stress fractures occur when muscles are too exhausted to absorb shock. If the patient reports worsening pain when he or she puts weight on one leg, there is even more of a chance that there is a stress fracture. This suspicion can be confirmed through a bone scan or MRI. The usual sites for this kind of fracture are the femur and the pubic bone. A fracture of one of these bones can be particularly serious depending on its exact location. A fracture at the part of femur that is near the hip joint requires vigorous treatment, as it can be debilitating. Often, abrupt changes in an athlete’s training can put him or her at risk for a stress fracture.

Bursitis Pain

Bursitis is one of the most common cause of pain in the hip and groin. This condition occurs when a bursa becomes inflamed. Healthy bursae reduce friction between bones and tendons or between muscles, but repetitive motions can irritate bursae and contribute to bursitis. If an athlete notices pain on the outside of the hip area, this may be trochanteric bursitis. If the pain is located in the groin or in the thigh, this is known as psoas bursitis, which affects the muscle that connects the femur to the lumbar vertebrae. Gently pressing on each area and observing the patient’s pain response should be able to help find where the bursitis is located.

Nerve Damage

Nerve injury can be a cause of pain as well, and it can be one of the hardest injuries to diagnose. People with nerve-related pain may complain of tingling or a burning sensation in the hip or groin areas. If a patient has a history of cycling, this may mean that she or she could have injured nerves due to overusing them.

Other Causes of Pain

There are many other conditions that can cause pain in the hip or groin area. Hernias within or above the groin can cause discomfort, as can irritation of the front pubic joint. Advanced urinary tract infections and other gynecological infections can cause pain as well. The occurrence of uterine tissue outside of the uterus is known as endometriosis, and this can cause discomfort near the hip or groin. Inflammation of the testicles or prostate can cause discomfort, and any swelling can possibly be due to testicular cancer.
