Hip impingement, or femoroacetabular impingement (FAI), occurs when the femoral head (ball of the hip) pinches up against the acetabulum (cup of the hip). When this happens, damage to the labrum (cartilage that surrounds the acetabulum) can occur, causing hip stiffness and pain, and can lead to arthritis.
A groin strain is an injury or tear to any of the adductor muscles of the thigh. These are the muscles on the inner side of the thigh. Sudden movements usually trigger an acute groin strain, such as kicking, twisting to change direction while running, or jumping. Athletes are most at risk for this injury.
A disorder in which the piriformis muscle in the buttocks irritates the sciatic nerve. Piriformis syndrome is a disorder of a narrow muscle located in the buttocks. Symptoms include pain, tingling or numbness in the buttocks and down the leg, which may worsen after sitting for a long time, climbing stairs, walking, or running.
Snapping hip is a condition in which you feel a snapping sensation or hear a popping sound in your hip when you walk, get up from a chair, or swing your leg around. The snapping sensation occurs when a muscle or tendon (the strong tissue that connects muscle to bone) moves over a bony protrusion in your hip. We differentiate between internal snapping hip, external snapping hip and snapping hip due to cartilage injury.
Many conditions and diseases can cause pain in the buttocks, commonly known as butt pain. Causes of pain in the buttocks range from temporary annoyances, such as bursitis, bruising, piriformis syndrome, muscle strain, and shingles, to more serious diseases with long-term consequences, such as cancer, arthritis of the sacroiliac joints, and herniated disc with sciatica.
Trochanteric bursitis may affect the hip's outer area or the outside part of the upper leg, from the hip to the knee along the thigh. Symptoms include pain on the outside of the hip that is worse with activities such as standing, walking or running.
