Hip Pain: Causes and Treatment

The hip joint is designed to withstand repeated motion and a fair amount of wear and tear. This ball-and-socket joint -- the body's largest -- fits together in a way that allows for fluid movement.

Hip

Whenever you use the hip (for example, by going for a run), a cushion of cartilage helps prevent friction as the hip bone moves in its socket.

Despite its durability, the hip joint isn't indestructible. With age and use, the cartilage can wear down or become damaged. Muscles and tendons in the hip can get overused. The hip bone itself can be fractured during a fall or other injury. Any of these conditions can lead to hip pain.

If your hips are sore, here is a rundown of what might be causing your discomfort and how to get hip pain relief.

Causes of Hip Pain

These are some of the conditions that are most likely to cause hip pain:

  • Arthritis. Arthritic conditions such as osteoarthritis and rheumatoid arthritis are among the most common causes of hip pain, especially in older adults.  Arthritis leads to inflammation of the hip joint and the breakdown of the cartilage that normally cushions your hip bones. The pain gradually gets worse as the arthritis progresses. People with arthritis also feel stiffness and have reduced range of motion in the hip.
  • Hip fractures. Fractures of the hip are a particular problem in elderly people. With age, the bones can become weak and brittle. Weakened bones are more likely to fracture during a fall.
  • Bursitis. Inflammation of the small, fluid-filled sacs (called bursae) that protect muscles and tendons is usually due to repetitive activities that overwork or irritate the hip joint.
  • Tendinitis. Tendons are the thick bands of tissue that attach bones to muscles. Tendinitis is inflammation or irritation of the tendons. It's usually caused by repetitive stress from overuse.
  • Muscle or tendon strain. Repeated activities can put strain on the muscles, tendons, and ligaments that support the hips. When these structures become inflamed from overuse, they can cause pain and prevent the hip from functioning normally.
  • Cancers. Tumors that start in the bone (bone cancer) or that spread to the bone can cause pain in the hips, as well as in other bones of the body.
  • Avascular necrosis (also called osteonecrosis). This condition occurs when blood flow to the hip bone is reduced and the bone tissue dies as a result. Although it can affect other bones, avascular necrosis most often occurs in the hip. It can be caused by a hip fracture or dislocation, or from the long-term use of high-dose steroids (such as prednisone), among other causes.
