I have been running a fever off and on for 1 week; highest 103.8 Tues. Thursday ended up with purple spots on my lower legs and going over the top of my feet. Friday started itching on the bottoms and side of feet, knuckles, and down my arms. Now have a sore throat and low grade fever, maybe a little bit of sinuses. I am also diabetic, but just taking metformin and was running very high, 596, so now am taking insulin. What is wrong with me?
