Different kinds of itchy red spots on body

Hello my name is Ricky...

I've been getting different types of "rashes" on my skin for about 1 and a half month... When I say "different types" I mean that they are not always consistent in the way the appear/look... I got an appointment with a dermatologist to check it out, but I wanted to see if anybody here could have at least an idea of what it is and what could be causing it (even if it's generally).

The marks normally appear on my wrists (mostly below where the palm starts), fingers (mostly between nails and knuckles), knees, shinbones, forearms and below the pecs (in the area where ribs are mostly noticeable).

They sometimes appear on my neck and back, but not nearly as much.

The marks appear, itch, and then they disappear completely after a while... Only a few pimple-like marks stay on my skin more than usual, but they also end up disappearing completely.

I'm linking to some pictures I took, so you guys can have a better idea of how they look and vary.  

Thanks for everything in advance.

Here are the pictures...

Hello,

From the symptoms it can be urticaria or hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours or days.

Apply calamine lotion and mild steroid cream and take some oral antihistaminic like Benadryl. If the symptoms persist then please get it seen from a dermatologist. I hope it helps. Take care and regards.

Thanks for the info... I'll just wait for them to go away.
