I thought I was getting bronchitis but it has ended up being pneumonia. I decided to put off allergist appt. until I get all of this daggone fluid out of my lungs. Have rescheduled for 2 weeks from now. I was reading recently an article that said diabetes can cause hives. I've been tested repeatedly for diabetes and tests say I'm not diabetic, prediabetic, nada. But I have pn, the hives, etc. It's sure got me going hhhhmmmmmm.
