I'd go with that 'instinct' and gut feeling, personally.... Dunno tho this is a bit more outta my range than normal.

Have to ask one big hard question tho.... Would the tests if positive, result in any postive viable treatments? Or, merely more formally assert more of the same therapies and meds that you are getting now....

THAT is one of the harder things I've had to accept with my own med issues, that of knowing there isn't much more that they can 'DO' for me beyond what they're doing. Beyond that, there is a round of diminishing returns and so forth. Not to mention some anger about the whole thing, but that's another topic I think.

Hugs and hope for sure! - 's - j
