Hi Jaime,

Flouroscopy is an xray machine so to speak. When they are giving injections into the spine; facets, selective nerve root injections, ESI's, the docs SHOULD ALWAYS use the xray. Otherwise they can't see by blindly going in. But for trigger point injections BY the nerves or as in my case, in the scalp, no you don't need it. I think it all depends on what injections a person is speaking of. For instance I see ESI alot whent he person means another type of injection. Anyway, when dealing with the SPINAL injections there is no way a doc should be going in without the use of Flouroscopy guidance. If a doc says he can do the SPINAL injections without using xray, RUN...don't walk! But again, if it is a blocking of the nerves in the scalp and that sort of thing that's different. And you are right; the doc palpates the area, finds the nerve and then blocks it. I have had plenty of those done too. But eventually it was determined it was all coming from the spine and THAT is when Flouroscopy was used. It is just basically a LIVE guided xray as they perform the injection and is usually a C-arm that goes over the area to be injected; they take pics too as they go along and guide the needle placement.
