Two possible causes of hip pain are fractures and insufficient blood flow to the hip (aseptic necrosis). A hip fracture can change the quality of your life significantly. Fewer than 50% of those with a hip fracture return to their former level of activity. In addition, while recovering from a hip fracture, several possible complications can be life-threatening. These include pneumonia and a blood clot in the leg, which can dislodge and travel to cause a clot in the lungs. Both are due to immobility following a hip fracture and hip surgery. Hip fractures become more common as people age because falls are more likely and bones become less dense. People with osteoporosis can get a fracture from simple, everyday activities, not just a dramatic fall or injury. Aseptic necrosis can happen if you have been on steroids for a long time or you have sickle cell anemia. Injury and regular use of alcohol also increase your risk. Legg-Calve-Perthes disease is a type of aseptic necrosis that happens in children. Other possible causes of hip pain include: - Arthritis -- often felt in the front part of your thigh or in your groin.
- Trochanteric bursitis -- inflammation of the bursa that sits on the outside of your hip joint. This hurts when you get up from a chair, walk, climb stairs, and drive.
- Tendinitis from repetitive or strenuous activity.
- Strain or sprain.
- Low-back pain such as sciatica.
- Infection.
