If one wanted to do injections all in the periphery (no spine), just joints, nerves, muscles, tendons, what are your thoughts on whether advanced training (Spine or Pain fellowship) is needed? I realize that's a two part question - one is, can you get the skills needed in residency alone, the second is, even if you have the skills, will an employer allow you to perform the injections. Let's assume one gets adequate exposure in residency (100's of USIs) and focus on the second part - will hospitals, AMCs, PP, let you do (and bill for) the injects?. Thoughts?
