Hot boobs?!?

Kelsey • Mommy to precious daughter Chloe, born at 23 weeks gestation 💞👶🏻
So this is weird and super random, and I was wondering if this has happened to any of you. I was getting ready for bed at the end of the day, and as I was getting undressed my arm brushed against my boob and it was super hot! I felt the rest of my skin and the rest of my body (even my tummy right under my boobs) was cool/normal feeling. But still the extremely hot boob temperature remained, even feeling weirdly hot to my husband. Has this happened to any of you? What in the world could it possibly mean? I'm 18 weeks pregnant with my baby girl.
