No - that's what's so odd. In 59yrs, I've been allergic to poison oak/ivy (which I recognize easily) and the allergy has lessened over the years. I've been allergic to bee stings but not seriously so. Nothing else has ever bothered me. I've used all sorts of chemicals painting, stripping furniture, etc. without any problem. I guess something has tripped the reactions.
Have you just been sensitive to this one thing this one time? Or other things too, lately?
