Confusion between PUPPP and ICP

Patient: Hi, I’m 35 weeks pregnant and a couple of weeks back I developed severe itching and a rash on my tummy, which has now spread on my thighs, shins, buttocks and arms as well. There is no itch on my palms or soles however. I did some reading up on PUPPP and ICP. My doctor seems to think that it’s liver related, though my LFT values are all in the normal range. He has prescribed Udivil for ten days. I’m confused because I feel it is PUPPP, even though the rash on my legs and arms are not very PUPPP-like, there are independent scabs.

Symptoms: Itching, rash, 35 weeks pregnant
