It's still swelled up even three days later? Does it still hurt? I'm thinking now you might be allergic to the venom, in which case the effects of the bite will be worse than for most people. It is also possible you're not allergic and that you just got a crapload of venom (for a garter snake). Although the situation is not dangerous and the swelling should go away over the next few days, you might try calling up your doctor and seeing if there is anything you can do to ease the discomfort. Here is a good article on garter snakes as "warm" snakes: www.anapsid.org/duvernoygland.html
