Blistering rash week 3! 30 wks preg


so I’ve had this blistering burning itching rash on my feet and hands and within the last week spread up my legs I’ve done LITERALLY EVERYTHING YOU CAN THINK OF TO RELIEVE IT NOTHING WORKS. It’s still today continuing to spread. It’s not pupps it’s not from a plant not from a bug not eczema they just have no clue what it is I’ve been seen 4x for it and I’m at the point I can’t tolerate it anymore my skin looks so gross they’re blisters everywhere, bleeding. I just don’t know what to do 😭
