Itchiness Driving Me Crazy!!!

Mari Ann
So basically for the last week I have been itching ALL over at the end of the day. I had PUPP with my last pregnancy from 28wks-6wksPP. It was awful, but this is different. Also, my hands and feet are super hot and swollen. Any ideas as to what this could be? It's driving me insane. I feel like I'm going to scratch my skin off!! TIA!!
