Terri, very sorry to hear that you relapsed after initially feeling better. Hope you can REST. Rest and get better.
I remember that your hubby and I have the same condition: Idiopathic Chronic Uticaria. It means chronic hives but we don’t know why. I take a Zyrtec and a Pepcid every morning, to keep it at bay. It was pretty much gone until I started taking the cancer med. Now I’m itchy again. Pepcid is a stomach med, but our excess histamines are made in the stomach. So the Pepcid keeps them under control. Works well for me, plus it fixed my acid stomach.
