Painful red rash

April

Anyone have a pregnancy related rash down there? I have one small area on the side of my leg/butt/vagina and it’s so painful I could scream. Midwife said it’s an allergic reaction but it doesn’t itch, it hurts so much I can hardly walk sometimes. It’s red, raised and bumpy but not fluid filled. Anyone know?! The white in the pic is Benadryl cream that isn’t helping at all.
