That could be what it is from because my meds were switched in April from Zantac & Protonix to Protonix 2x a day so that could be the cause of my rash since that is about
the time it started. Now I a currently on Nexium. Will watch this closely and see if it goes away or gets worse. I always have the weirdest most remote side effects from meds. One example is Alegra which caused horrible lower back pain. Catch you later. I'm going to attempt to get some sleep tonight with this awful heartburn. Barb
