I am not aware of any connections between tests & nausea - this sounds like something you should ask you Dr about
if it continues much longer. Are you taking anything besides MTX? Some of our meds they tell us to take an antacid with it because of side effects, but you should check with your Dr.
I doubt the hives have to do with the nausea, but the hives may have something to do with the MCTD. It may be that the testing caused even more inflammation that what they found and that the inflammation is causing the hives. If they don't go away soon I suggest checking in with your rheumy to see if you can get them under control.
