I don't have hip pain when walking/running/biking but do when sitting down, what's wrong?

Hip Imingment?: There are many possible causes of your symptoms and a full history, physical exam, and imaging studies may be required to confirm the diagnosis. One possibility is femoroacetabular impingement, which is an abnormal pressure of the ball/neck of the hip joint with the socket. Many people complain that the sitting position, when the hip is flexed, causes the most symptoms.

It may not be your: Hip that is the source of your pain but your lower back. Sitting can generate up to 4 times your body weight across the discs of your lower back while sitting takes the load off your hip joint. Back pain usually responds to exercise like walking, biking and running. See your doctor for further evaluation or an orthopaedic surgeon or physiatrist..
