Spinal injections are recommended for the treatment of chronic back or neck pain. They relieve pain by blocking the transmission of nerve signals between specific areas of the spine and the brain. The injections usually contain local anesthetics, steroids, or narcotics and are administered into the spinal joints, nerve roots or affected soft tissues. Complex nerve blocks may also be performed. Spinal injections are performed with x-ray or ultrasound guidance. Specific procedures offered at PSSP for spinal conditions are listed and described in more detail at Spine Conditions.
