I had this years ago when I was in high school They ran everything in the world on me. I was in the hospital for a week and a half. Came home the same way as I went in. Except on crutches My legs were swollen black and purple I had so much pain. They had painful nodules all over them etc. Well they finally decided that I had had strep throat before all this happened and had been on antibiotics but they said the antibiotics didn’t kill all the infection and so it then had drained down into my legs. Sounds crazy but I finally got better.
