Kyphosis
Kyphosis is a spinal disorder in which an excessive outward curve of the spine results in an abnormal rounding of the upper back. The thoracic spine should have a natural curve between 20 to 45 degrees. In the case of a severe curve, the condition is called "hunchback." Symptoms include rounded shoulders, visible hump, mild back pain, fatigue, spine stiffness, weakness, numbness or tingling in the legs, loss of sensation, and shortness of breath.
