The hip joint is designed to withstand a fair amount of wear and tear, but it’s not indestructible. For example, when you walk, a cushion of cartilage helps prevent friction as the hip bone moves in its socket. With age and use, this cartilage can wear down or become damaged, or the hip bone itself can be fractured during a fall. In fact, more than 300,000 adults over 65 are hospitalized for hip fractures each year, according to the Agency for Healthcare Research and Quality.
Outer hip pain and lateral hip pain, though typically not cause for alarm (as the hip is not sitting near any major organs like the heart, lungs, kidneys, or liver), can be a sign of a serious bone condition, such as arthritis in the back, rheumatoid arthritis, osteoarthritis, or tendonitis but can also indicate a more serious bone condition like a fracture, labral tear, or conditions such as snapping hip syndrome or osteonecrosis.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
