Itch, Itch, Itch!

My skin has been itching like crazy for the past several weeks.  The intensity comes and goes, but definitely increases when my body temperature goes up, like from sun exposure, hot water, or humidity.  The worst is my legs and arms.  I haven't noticed any itching any where else.  It's almost like the reaction I have to certain fabric softeners and some dryer sheets, like Downy or Snuggle.  I get these tiny little bumps on my skin, not red or noticeable, and they become more pronounced the more I scratch....unless I scratch enough to remove the top layer of skin, oops.  (Yeah, my doctor already scolded me on that one)  I think I might have this -"prurigo of pregnancy".  Lovely.
