just because your posts are the most annoying i have ever read, i will answer this for you. facet arthropathy is irrelevant. arthropathy is common without symptoms. facet pain comes from the facet capsule, which is likely stretched a bit with manipulation, however this is difficult to prove. it is the reason why some people do great with manipulation. i am no fan of chiropractic, but there are multiple trials that show efficacy. its equivalent to p.t., which is in general a total sham the majority of the time. sleep you are a resident with a lot yet to learn. you ask questions like a resident who doesn't know a thing about actually treating a patient. you will not bat 1.000 treating pain. get some humility while you can because you need it badly.Dont even try the 'young' guy training on me bud. No offense, but your knowledge of anatomy/physiology is likely an inkling compared to even an intern's from a US medical school. Not a pissing contest, just the facts.
Secondly, let's see..epidurals help with the inflammatory process associated with herniated discs. How again does your massaging or manipulaton do that again? You'll likely say something that give a massage say. "it increases blood flow and lymph flow and take the toxins away'.
And since your name is facet..what does your manipulation do for facet arthropathy? How are you blocking pain that originates there?
Yah, I'll light a candle and sing Kumbaya and wait for your responses.
