The clinical manifestations of osteoporosis include three main points. The first is pain, thus osteoporosis will definitely cause pain. This pain may be localized or it may be widespread. The second is spinal deformation, which can result in forward bending of the spine, scoliosis, or even spinal shortening, which is a reduction in height. The third point is pathological fractures, which are characteristic of osteoporosis. These fractures occur due to insufficient bone strength caused by osteoporosis, and sometimes even low energy or minor external forces can cause fractures, such as pulling a door or being struck by a car door. Therefore, osteoporosis definitely involves pain, and pain is one of the main symptoms of osteoporosis.
