injection
who's performing the ESI? Is it the PM? Is it the Ortho? The caudal approach will bathe the general area probably from L5S1 up I believe and then if you're going to get a series of 3 injections they can see if doing one level say L5S1 helps and if not maybe the next time L4...
It could be the anular tear that's giving you the probs or the broad based disc bulge or both.
A discogram seems to help depict the most painful level re disc problems. Have you had one done? I have 3 and all pointed to L5S1 being my worst level so we went with ESIs at that level for a number of years and then later it seemed I autofused at that level and L4 was worst so then transforaminal approach was used at that level (based on MRI) and that helped significantly.
I also had L3 done as I have an anular teat at that level tho no help whatsoever so it was determined that wasn't a level that needed ESIs and for 10 years that was accurate apparently (got them for 10 years and they helped my symptoms significantly).
