Did you take you temperature? I couldn't figure out if you meant you had or not. Your leg is hot but is it painful? Red? Swollen? Hard? What about your toes - can you move them? Feel them? If the answer to most of these is yes then I'd get yourself checked out just to be on the safe side. Better safe than sorry.
If not, then try to relax - keep icing and drinking plenty. You could be having a reaction to the pain meds, they are known to cause hot sweats. If that doesn't settle by Monday, the speak to your doctor about it on Monday.
And finally - day 6 - yeah, you'll feel this bad! Our bodies don't like being chopped about and they have a habit of letting us know!
