Its an inevitable fact about aging: Sooner or later, your back is likely to act up.

"If youre not responsive to traditional treatments, these may be things to investigate, but it should be a team effort between you and your doctor to determine which treatment you may be a candidate for," says Russell DeMicco, DO, a staff member at Cleveland Clinics Center for Spine Health.

The underlying cause of your back pain determines whether one of the newer treatments can help ease your discomfort.
