Osteoarthritis

Your vertebrae have slippery tissue on each end that helps your back flex without friction. If that cartilage gets rough or wears down, the vertebrae start to rub against each other, and it makes your back painful or stiff. Women are more prone than men to get osteoarthritis in their backs, and it tends to get worse over time. Your doctor can't reverse it. But painkillers, therapy, and exercise help ease the symptoms.
