Trochanteric Bursitis
Trochanteric Bursitis occurs when the trochanteric bursae, a set of fluid-filled sacs that cushion your hip bone, suffers inflammation or injury. Your trochanteric bursae sit between the juncture where the trochanter of your upper thigh bone meets your iliotibial band. When these bursae become irritated, lateral hip pain often signals the presence of bursitis.
