Sensitive skin help!

Sensitive skin help? First off, I’m allergic to dogs/animals. The fur has always made me itch. But I’ve always been an animal lover, we currently have about 10 dogs and quite a bit of other animals. We take in rescues. I clean my house 100 times a day because getting rid of the animals is not an option. But anyways, even when I don’t touch the dogs or even when I’m not at home I will get itchy. I won’t have a rash or bites or anything and it will come on out of nowhere. Sometimes it’s right after I get out of a shower (I use dove unscented soap btw) or if I get super cold, or super hot. It’s really bad at night when I go to lay down I guess maybe because I realize it more then. And it’s really bad a lot of times right after I shave. I always use a new blade and a special cream to shave with. There’s no bumps showing it’s razor burn. It’s mostly my legs, arms, and tops of my hands and feet. When I was in high school, I actually went to the doctor because the tops of my feet were so itchy It was causing scabs. The doctor accused me of being on drugs. Here I am over 10 years later still itching and I’m kind of intimated about going to the doctor about it again. Right now it’s particularly the backs of my legs and the top of my hands. Does anyone else have this or know what’s going on? I’ll use lotrimin spray, Neosporin, aloe Vera, or cortisone cream. It sometimes help but it doesn’t ever completely knock it out. I hate walking around with scabs all over me that I caused accidentally especially since it’s still so hot and I can’t where pants. If I get in the tanning bed, a week or so after my skin will clear up and won’t itch as bad. I hate having to get in the tanning bed just because I’m having skin issues. And BTW I can’t get in the tanning bed right now because I’m pregnant. So I feel ugly.
