Bursitis of the Hip
Bursitis occurs when a bursa becomes inflamed, and it is a common cause of pain to your hip
A bursa is a fluid-filled space that acts as a cushion between tendons, bone, and skin which helps your joints move with ease. There are over 150 bursae in your body, and several are found around the outer area of the hip, near the portion of your thigh bone (the femur) called the greater trochanter.
Inflammation of a bursa is caused by repetitive-use injuries, prolonged pressure, lumbar spine diseases, rheumatoid arthritis, and sometimes infection. It can affect anyone at any age, but is most common in women and the middle-aged. The main symptom is aching pain over the part of the outer hip. The pain worsens with movement or pressure and may travel down the outside of the thigh toward the knee. Pain caused by pressure at night can make sleeping very difficult.
Your doctor will be able to diagnose bursitis when he or she physically examines the specific area causing pain and tenderness. However, an X-ray may be taken to rule out other causes.
