@yeeko I am VERY picky about who does injections in/near my spine, and how they are done. I have muddled along pretty well for years, but disc degeneration and stenosis are worsening, so I have an epidural scheduled next week. My ortho and I are "on the same page" as far as methodology - a pain management doc will do an x-ray guided injection, referring to the notes from the latest MRI.
Did your doctor use imaging to guide the injection? If not, you may want to ask for a different practitioner?
