Haven't gotten any rashes yet but I definitely feel your pain..I live in AZ
I live in California also, this heat is crazy especially for a 8 month pregnant lady...
I also live in California, since I have been pregnant I get rashes under my arms. This weather is extremely crazy. It's currently 101 and we are expecting a thunderstorm any moment
Last week I got a wicked rash on the top of my foot.. I live in maine and its been hot hazy and very humid for the last 2 weeks. I called the dr due to the fact that I was gonna scratch my foot off with the intense itching!! I was a bit nervous at what it could have been. We figured out ( or so we believe) that its my eczema that I usually get on my elbows during july and august. It had moved locations to my foot and was about amonth late showing up. Pregnancy does weird stuff to our bodies!!
