Pregnancy Rash; PUPPS ?

Yessenia

Currently 21 weeks. 2nd pregnancy.

It’s been 2 weeks since I developed a rash and I first developed an itchy hive like rash between my thighs; I thought it was a HEAT rash but it doesn’t go away ; then it appeared on my hips now it’s on my arms and feet ;

Does PUPPS develop on one’s feet also ?

And, it seems to get worse at night. Has anyone else experienced this?

Went to the OBGYN and was told it looks like an allergic reaction to food and was prescribed a steroid cream. I’ve never been allergic to anything. I was referred to a dermatologist and now I’m on a waiting list to even see one.
