Itchy

Hi ladies,
Does anyone happen to have experience with itching?
I got a few red bumps a week ago that itched occasionally. It got worse day by day, and now my entire lower legs and feet are covered in bumps. Some are red, and some don't really have a color. I'm also starting to get a kind of small blisters. I can't sleep anymore because the itching is so bad. I'm also getting itching on my upper legs and arms from time to time. I called the midwife last Friday and explained it; she said it's probably PUPPP syndrome, there's nothing you can do about it, and it'll go away on its own. A bit weird because she hadn't even seen anything.. I also called the GP on Friday and went there 2 hours later. Strange guy I had, and he said it was inflamed hair follicles. He said yes, go get cooling cream, but that doesn't really help, so we'll just have to wait and see. Meanwhile, I went looking for what I could get myself. I've now used cooling cream, Levomenthol gel, Lidocaine Levomenthol gel, and Cetirizine (pills for allergies) but no effect. 10 minutes after applying the cream, I have so much itching again. It's enough to drive you crazy!! Anyone has tips by any chance?? By the way, I'm 32 weeks and 2 days pregnant.
