I have girls, and have an allergy to them. The first time it happened was shortly after I got my first two girls. I got a severe reaction, my hand and arm blew up to twice the size from hives. I went to the hospital and was given prednisone and a cream. It still took weeks to clear up . Since then, I have taken precautions to minimize it. I trim nails, I wash my hands a lot, and wear long sleeves when possible. I still get reactions sometimes, even with no scratches, but it's nothing like the first time. My hand usually gets hot and itchy, then breaks out. I could never not have rats because of it though.
Oh my god, that's what it was. That happened to me recently, but I didn't know what caused it, and my I ended up covered in hives with my hands and feet swollen like CRAZY! It was actually right after Fred bled on me a lot (toenail injury).
