Not being rude, however, just because you go to Emergency Room doesnt make your specific injury or complaint an actual emergency.
Believe me, with many, many, years of experience in and out of hospitals I can say your not going to be treated like gold coming in TO THE EMERGENCY ROOM with a bite on your foot unless your life is in immediate danger.

Again I feel your pain and not trying to be rude but just stating the facts! Hope your foot gets better.
