Skin health question about hives

A while ago, small rash-like bumps appeared on the back of my neck. It was itchy, and when I scratched it, some blood would form. It didn't hurt, so I just brushed it off, thinking it was just the change of seasons. However, rash-like bumps started appearing in various spots on my body as well. They are itchy, and they itch even more when my clothes brush against them. I don't think it's an allergy, and since this is the first time this has happened, I just applied some ointment I had at home. The ones on my body usually go away, but the rashes on the back of my neck and stomach haven't disappeared, and it has been two months now. When I asked acquaintances, they said they had similar experiences. They mentioned that even if you go to a dermatologist, they just give you ointment and there isn't really any specific treatment; they just come and go, then come back again. Will it just get better on its own? I'm getting a bit worried because it's dragging on, but surprisingly, there aren't many dermatology clinics that specialize in skin conditions. I hope it goes down without leaving scars, but I am still worried.
