What is this?
Christopher P. Silveri, MD
Judicious use of selective injections can provide both therapeutic and diagnostic benefits. Each shot is tailored to the specific anatomical area in question and should never be combined in the same sitting. Each shot should be performed to confirm or rule out a potential site of pain generation. In such an organized fashion a spine specialist may be able to clarify what was previously a diagnostic dilemma.
