PUPPP remedies?

I think I have developed PUPPP. The under part of my belly has gotten quite itchy and red. I’m 31 weeks 5 days pregnant and already suffering from a ton of other issues such as high BP, GD, acne all over my body, beginnings of preeclampsia, etc.

What can I use to help smooth this itch? I tried lotion for pregnancy and it’s semi helping. I am starting to get new stretch marks and I already have a ton of existing ones from when I was pregnant with my daughter over 10 years ago.
