New apartment, new prospects, new ways for my skin to break out with violent painful burning itching

I moved into a new apartment. It's furnished, clean, chill. Also I break out in hives when I lay in bed with the fresh bedding provided to me. Currently washing a blanket but I've just ruled that one out as a cause. I'm out of detergent for washing the remaining sheets and snowed in. I think I'll sleep in this chair :)
