Since lupus can affect the internal organs, I would take her to see another rheumie until you find one that will try something other than or in addition to an NSAID like
meloxicam. (I also take
meloxicam, but in conjunction with three other meds for RA that go after the disease process itself, not just treating the symptoms like meloxicam alone).
Blood work is only one of many diagnostic tools, not the yes-or-no definitive answer.
