They’ve done ANA twice. Always high according to labcorp. Rheum did full panel for autoimmune and everything is negative except high RNP antibody which looks like MCTD when I google. I try hard not to go down the google rabbit hole but it’s really all I have at this point. Just not sure how high the RNP needs to be to get a diagnosis. I live with pain in every part of my body every single day. OTC meds don’t touch it so I gave up on that. They took my gall bladder out and that did nothing. Gastro gave me PPI which made it worse. Enter Xanax to sleep and even that doesn’t work most nights. Seems like it’s all just guesses and Im trusting these docs with my life. Super frustrating. I appreciate these replies so very much.
