Hip-related pain is not always felt directly over the hip. Instead, you may feel it in the middle of your thigh or in your groin. Similarly, pain you feel in the hip may actually reflect a problem in your back, rather than your hip itself.

See: Low back pain

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 -- 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

• Try to avoid activities that aggravate the pain.
• Take over-the-counter pain medication, like ibuprofen or acetaminophen.
• Sleep on your non-painful side with a pillow between your legs.

A hip fracture is considered a medical emergency. Therefore, if suspected, you should be seen right away.

As the pain improves, gradually begin to exercise. It is best to work with a physical therapist to learn proper exercises and how to advance your activity. Swimming may be a good option because it stretches the muscles and builds good muscle tone without straining your hip joint. However, swimming does not build bone mass. When you are ready (a physical therapist can help determine that), slowly and carefully resume walking or another activity against the resistance of gravity.
