I apologize for my ignorance but I’ve seen forum posts on here as well as job postings talking about interventional and non-interventional pain. I understand the concept as far as the difference in their day to day work but am curious if there is any difference in their training. Are there specific fellowships for interventional and non-interventional or are they combined? Also, are “interventional” positions reserved for anesthesia or can someone from PMR, neuro, psych etc also focus on interventional pain? Thanks in advance.
