Adductor tendonitis is usually an overuse injury; on occasion it may be developed suddenly due to a forceful contraction of the adductor muscles. This typically occurs during rapid acceleration as in running and changing direction. Pain may increase with squeezing of the legs together or when moving the affected leg away from the midline of the body (abduction).

A groin strain occurs due to too much repetition or high force, with this force one or more of the groin muscles can tear. The tear can range from a small partial tear with minimal pain and minimal loss of function, to a complete rupture of one or more groin muscles resulting in severe pain and marked loss of function. A groin strain usually causes a sudden sharp pain or pulling sensation in the inner thigh which may cause swelling, muscle spasm, weakness, tightness, tenderness and bruising in the inner aspect of the thigh and groin.

The pain associated with hip arthritis is typically felt in the groin, front of the hip and/or the buttock region. Occasionally pain may be referred to the thigh or knee.

Hip flexor strains occur due to a sudden contraction of the hip flexor muscles; this can cause small partial tears where there is minimal pain and loss of function, to a complete rupture involving a sudden episode of severe pain and significant disability. Common symptoms include sudden and sharp pain or pulling sensation in the front of the hip or groin.

A labral tear often occurs traumatically from a sudden change of direction and twisting movement. A labral tear can also occur over time through gradual wear and tear associated with overuse. Often an audible sound can be heard at the time of the injury or a feeling of a tearing sensation. Pain is usually felt in the groin, hip and / or buttock. Symptoms typically increase with weight bearing activity and twisting movements of the hip.

Osteitis pubis is usually an overuse injury, which commonly occurs due to repetitive or prolonged activities. Common symptoms are groin pain that develops gradually overtime. Pain may be experienced on one or both sides of the groin.

Trochanteric bursitis most commonly occurs due to repetitive or prolonged activities or due to prolonged pressure on the bursa (such as excessive side-lying particularly on hard surfaces). Common symptoms are pain in the outer aspect of the hip. Pain may also radiate down the outer aspect of the thigh as far as the knee.
