Trochanteric bursitis is an inflammation of the bursa, a small fluid-filled sac that cushions the greater trochanter (the bony prominence on the outer hip). The bursa helps reduce friction between bone and soft tissues during movement. When it becomes irritated or inflamed, it causes pain and tenderness in the hip area. This condition is one of the most common causes of hip pain, particularly in middle-aged and older adults, affecting women more frequently than men.
- Aching pain on the outer hip that worsens with activity
- Mild tenderness when pressing on the hip
- Slight discomfort when lying on the affected side
- Morning stiffness that improves with movement
- Occasional sharp pain with certain movements
