PUPPP please go away!!

Hi mommies! Just wondering if anyone had PUPPP before? First time pregnant I'm on my 36 weeks coming to 37 soon.. I couldn't stand this itchiness around my belly, my neck, my back.. I did went to GP to ask for some lotion to ease the itchiness while waiting to see my gynae appointment next few days. It didn't help much! I really don't know what to do now. I couldn't sleep! It triggers more when I'm sweating.. Help please!!
