Hey y'all! I am looking everywhere for information about one of the many procedures I have had done (post op.). The one I am having trouble locating info on has the abbreviation called a PLA. When I was having my last procedure done under conscious sedation, I have a brief memory of looking at the screen of the X-ray and seeing a white line above my spine. I was told it is a catheter that is supposed to loosen the scar tissue. I don't understand how this works or why I had no (noticeable) puncture wounds on my lumbar spine. I have also had facets. My pain management doctor doesn't explain anything and when I do see him for a follow up, I see him for 1 minute max. HELP! Enlighten me please!
