Puzzled

I missed some of the symptoms. She ran a 103 fever the first time I took her in. She also had a abcess popping out of her hip also as well as her elbow. All four of her feet were swelling to the point where they broke out in sores in-between her toes. The only thing that changed when I brought her home from the Vet was after 4 days I took her off the steroids. She was doing great but on the 6th day went right back to being lethargic & unable to walk. That was on the 6th day I brought her home from the Vet. When I brought her back she was running a 104 fever. Hopefully we will know something today from the cultures the Vet sent off. Also, the Vet pulled some fluid from the swelling on her ankles & it was a opaque fluid. No blood in it.
