We've gone through this. Just last year with my college son. I had to go get him from college, he was completely incapacitated and could barely get out of his bed- never mind going to classes. It can be MUCH WORSE for boys/men... because well... they don't wash their hands before they go to the bathroom (TMI I know, but it will spread *there* - and it's extremely painful once it spreads there).
Go to the doctors and get steroids. When it gets this bad it's really the best way to treat it and do it SOON. We've also tried the natural route and it just doesn't work fast enough when it spreads like that. For future possible outbreaks get RusTox homeopathic pills and taken them religiously in the spring. It does work. But for now, just bite the bullet and get the meds from the doctors.
