I finally got my self up from the lounge chair and went to the doctor. I was expecting him to say it was the flu. To my surprise, it was pneumonia and I spent three days in the hospital. I could have died because of my hatred of needles.
If you feel sick with a cold/flu for more than three days, go to the doctor as soon as you can. It could be pneumonia. Everyone's pain tolerance is different and so you need to make sure there's not something more going on.
