Leg Hives

I have had hives on my legs, all below my knees for about a month and a half now.  My allergist said it was something called "vesticularitis" dont know if that is spelled right or not.  He gave me prednisone to take for about 2 weeks and said they would go away.  I'm off the medication now and they are still there.  They are only on my shins, and not anywhere above my knees.  I talked to my primary care doc and they said they didn't know what to tell me.
This is really scaring me because I don't know what this is.  My allergist told me if they didn't go away or if they came back then I might have some sort of disease.  My follow up appt with my allergist isn't until July.
These hives don't itch, burn, or have any side affects.  They are just there.  After taking prednisone they became less red, now they are darker.  I have never had anything like this before.
I want these to go away because they make my legs look horrible.
Can ANYONE give me an answer to what is wrong?
