Spinal injections are used in two ways. First, they can be performed to diagnose the source of back, leg, neck, or arm pain (diagnostic). Second, spinal injections are used as a treatment to relieve pain (therapeutic).
Most spinal injections are performed as one part of a more comprehensive treatment program. Simultaneous treatment nearly always includes an exercise program to improve or maintain spinal mobility (stretching exercises) and stability (strengthening exercises).
