Yuck!!!

I think I have been exposed to poison ivy! For the past 5 days, I have had an itchy, bumpy, red, swollen, blistery spot on my arm...and today it is oozy, scabby and still very yucky! I also have 9 little bumps on my other arm and a few on my legs. I am not sure it is poison ivy, but it sounds better than scabies, lice or mites!!!
