Oh no, not again

I came home last night, after a long stressful week, and after I finished vacuuming cat litter from the sun porch I hopped into the shower. What I saw in the mirror almost brought me to tears. After years of fighting them I really thought I had put them behind me. I am talking about the rashes I used to get under and between my boobs. They are heat rashes. Imagine my surprise to find one. I realize it may be aggrevated by both the extreme heat outside and my poor posture inside, but really?
