Hip joint pain in runners can be caused by trochanteric bursitis, says the Cleveland Clinic. This happens when the fluid-filled sac called the bursa of the greater trochanter becomes inflamed due to overuse. The greater trochanter is a bone that juts at the top of the thigh bone.
Trochanteric bursitis can be treated with non-steroidal anti-inflammatory drugs such as ibuprofen, says the Cleveland Clinic. The patient can also be given corticosteroids by injection to further reduce the inflammation and pain. A doctor might also send the patient to a physical therapist to learn techniques and exercises to help with healing. Normally, the bursitis resolves after a few weeks.
