Hello, My my son who is 27 year old male, was seen and treated for a ? spider bite to the face, was on abx ststeroids. he then spiked a temp to 103.4 a week later, along with a pinpoint rash over his body. treated for allergic reaction to Bactrim. was given new abx and steroids and pepsin. this was Friday. He now said that his palm of his hands and feet are really red and burning. I remember he had the same thing as a child when he was treated for strep but cant remember what they called it. Any ideas?
