I have been struggling lately. My body at random times, get covered in little bumps and they're insanely itchy

I literally want to itch my skin off. They generally are localized to one area at a time. My back, my stomach, neck, scalp, but never all at the same time.

In the picture you can see the bumps between my scratching.

Any recommendations on what to do?

Is it stress hives, or maybe something else ? Its been happening daily.
