Oh
my aching back! Most of us will say this several times over the course of our lifetime. Sometimes it's a chronic issue, a deep nagging ache that impacts daily activities. Other times, it's sudden and acute and amazingly painful, the result of a "wrong move" from lifting a small child, unloading groceries, or working around the yard. Back pain affects up to 80% of Americans annually and is the leading cause of disability worldwide.
