oh and i havent ever had these sort of thing b4

I had hives once, and what you described sounds like hives to me. I didn't have allergies either, mine were most likely caused by stress, that's what the Doctor said. She gave me a prescription of antibiotics, and it went away within a few days. Mine started at my wrists, looked like big red birth marks and they kept spreading. You should go to the doctor, I thought mine had cleared up but went anyways, and she said I still had them all over my body (I couldn't see them much, I was only itchy, but her trained eye saw that I had a rash that covered my entire torso, neck, and back.)
