I was weeding this past weekend and was yanking out these vines that seemed to look like roots with shoots and 5 leaves on them. When I went online today the shoots and leaves look loke virginia creeper. I now have a blister rash on my forearms. I was wearing gloves but because these "roots" went on forever I wrapped them around my arm to yank them out. i don't have any blisters anywhere but my arms. Could the virginia creeper have done this?
