Raw Rash on Ankles, Clear Fluid, Blister Like Bumps

I've had this rash which has been persisting for a few months now. I've gone to urgent care twice for it. The first time they gave me a steroid cream to use on it - which made me break out in even worse hives.These hives were all up and down my legs and inner thighs. I stopped using it and went back to urgent care. This time they gave me an antihistamine and a steroid pill. I was on both for 5 days and by the 5th day it seemed to calm down a bit, but when my prescriptions were up it came back full blown.

I'm a horse trainer and riding instructor and I wear boots almost daily with socks that go up to a tad above my ankles. At first I thought maybe it was an allergic reaction to the lining in my boots so I stopped wearing them and bought a new pair but it's done nothing to help it.  

The rash is insanely itchy and all over there are what feel like little pin head sized blisters that when get popped have clear fluid inside. At first the area was swollen and itchy now it's just itchy really red in color with the skin being dry and "scaly".
