Eight weeks ago a itchy rash started on my legs. My dermatologist put me on a course of prednisone which helped at the time but the rash returned and started spreading. One week ago dermatologist put me on triamcinolone .1% cream, legs wrapped in saran at night. Legs got a little better, stopped itching, but rash spread to arms and torso. Yesterday, my left arm became red, swollen and painful, but my temperature is my normal 97.6. Internist put me on cephalexin 500 mg and I have taken 4 so far. This morning my right leg is red, swollen and very painful and my temperature is 99.3
