Pain on the inside of the hip or in the groin is mostly associated with the hip joint itself, while pain on the outside or in the upper thigh and outer buttock involves muscles, ligaments, and tendons. Pain in the hip or leg may be caused by diseases or conditions in other areas, such as the lower back and is then called “referred pain”.
Degeneration of the hip joint causes inflammation and breakdown of the cushiony cartilage. Over time, the pain worsens as does stiffness and limited range of motion.
Hip Fractures —
Frequently seen in osteoporosis and therefore especially a concern, if an elderly person falls.
The liquid filled sacs that cushion the joints and ease friction sometimes become inflamed, causing pain in the hip joint.
Overuse of the hip joint often results in inflammation or irritation of the tendons, connecting the thigh muscles to bones.
Hip Labral Tear —
The labrum is a ring of cartilage encircling the outside rim of the hip joint socket. Repetitive twisting can cause a tear in the labrum, which helps hold the ball of the thighbone in the hip socket.
Avascular necrosis —
can occur when blood flow suddenly decreases to the head of the hip bone anchoring the thigh in the hip socket. Without blood supply, the cartilage and parts of the joints will die off, making the hip vulnerable arthritis Avascular necrosis can be caused by a hip fracture, certain diseases impairing blood flow or certain medications, among those prolonged use of high-dose steroids.
Knee Pain —
Degrees of knee pain vary widely depending on the location and severity of the symptoms, which may include swelling, stiffness, instability, redness and warmth, popping or crunching and decreased flexibility.
