I Have Had Hives For Almost 2 Weeks Now. They

I have had hives for almost 2 weeks now. They are around my waist, on my back, a few on arms/shoulder, and occasionally one one my face. I have tried to figure out anything I have eaten, been exposed to , but can't think of Anything? I'm using benydrl tablets and ant itch cream, but they keep coming back? Help.
