Sorry that you’re going through such a hard time. I have severe RA and have been on almost every drug out. Presently on RINVOQ and it’s helping so far. My last drug was XELJANZ. For me all the drugs cause me to break out in shingles so I keep a script of Acyclovir which helps me fight it off. I’m hoping that wasn’t what was happening to you with the itching. That itching episode has me very concerned. Did you call your doctors office and report it?? Good luck.
