Back troubles derail Roger Heinz

Disc degeneration, a common disorder of the lower spine, is a normal part of aging. It will affect most people and is generally not a problem by itself. Roger Heinz wishes his prognosis was as simple. There are days when Heinz, a junior at North Carolina, suffers from severe back and leg pain, has difficulty standing or walking and experiences weakness or numbness in his legs while sitting in class due to rapid disc degeneration. "I am 21 with the lower back of a 70-year-old," Heinz said. (Tallahassee Democrat)
