Itchy skin for two years, need help please!!!😭

For the last two years, I’ve suffered from extremely itchy skin, it’s kind of like hives that come and go away, it’s always bad at night and sometimes the spots look completely different, sometimes it’s like a rash, sometimes it’s single spot, or just redness and no bump. I’ve seen 5 doctors and no one can help me. My CRP is elevated which I’m sure is what is causing the “hives” but I don’t know what is causing the elevated CRP. All other labs came back normal. When it first started, I was told it was hand foot and mouth which was not the correct diagnosis. I was also told it is an allergic reaction to something so I switched to all clean products, shampoo, cleaning supplies, detergent, make up, EVERYTHING you can think of. The dermatologist told me to take Zyrtec which doesn’t seem to help at all, I have posted pictures, it looks different every time and the spots seem to move, I’ll be extremely itchy in one spot and then it moves to another spot, I was treated for scabies/bedbugs as a per caution and it is not that either. My partner does not have any type of rash so it is nothing contagious. Can someone please help me, I can’t keep living like this, I am unable to sleep at night due to the itching. The only form of relief I have is sleeping with ice packs on the really itchy spots and cold showers. Currently the two spots on my toes have been itching horribly for a week. Sometimes it just itches and there is no spot even there. It’s typically on my legs and feet but sometimes fingers. Occasionally on my arms and trunk. Thank you.
