I have started (in the last three years) having a temporary rash when my body gets heated
. Hot baths or excercise triggers the rash
, but after a few hours it goes away. It is blotchy and red, it is itchy, but the skin is not puffy. It occurs in splotches around my torso and down my arms, not on my legs.
I first noticed it after the birth of my daughter, who was born by cessarean, but it has not gone away even after my body has readjusted to not being pregnant.
