The findings on your MRI might not point to the structure that is causing your pain. By your description, the facet can be your pain generator. I understand how you feel regarding chiropractic but your symptoms might be well managed by manipulation. You need to find a good, experienced chiropractor who is gentile. Physical therapy is another alternative to manipulation.
The treatments you are currently involved with look to be beneficial although I am not clear how effective curcurium (tumeric)is.
