If you think you have the flu, you must seek medical attention. It's nothing to mess around with.
Hope you feel better soon.
You are not likely to die if you don't see a doctor, however there are alot of different flu strains out there, and some can be fatal. If you do not see a doctor, expect to feel worse than hell on wheels for about a week. I think you should see a doctor. - Blu
What sort of symptoms are you having?
