False injection results are common, especially with average docs but occasionally even withe the best needle jockeys out there. You're doing the right kinds of things to check to see if you've got bone damage or advanced arthitis or nerve damage. If nothing shows up with those tests, you might find that you're irritating the sacs that surround the facet joint. Each joint has a sac-like structure. If you have slightly wrong or too much movement, you can tug on those sacs and lead to facet pain, even without any visible arthritis. There's not much to do to deal with it, though. Core strengthening, rhizos to deal with the pain and possibly prolotherapy to strengthen the connective tissue at those levels are the only things I can think of.
