Oh shit!!!! You could be the first case of Smallpox since 1965. Better tell the folks down at WHO that its not been eradicated after all!
Well now, without meaning to worry you your symptoms may progress in a day or so to a rash with mucosal lesions. After a few more days these will erupt into pustules and if you're reay unlucky and have contracted Haemorrhagic Smallpox these pustules will burst and you will most likely exsanguinate.
Try not to trouble yourself too much I would suggest taking a couple of paracetmaol and going to bed with a hot water bottle. Get yourself setteled comfortably into bed then take a shot gun and blow your head off as you will most likely die sooner or later and the shotgun method would be less painful although it may be a little messier.
