Osteoporosis is often called the "silent disease," because most of the time, bone loss occurs without any symptoms at all. But when osteoporosis becomes severe, it can lead to fractures and a condition called kyphosis. Kyphosis is spinal compression, sometimes described as the "dowager's hump." Both fractures and kyphosis can be very painful. This pain is usually more severe than the typical "aches and pains" many people feel as they get older.
