Open Question: Piercing pain in center chest that comes and goes.?

To start off letmy said, I have been working with influenza forbthe in the past two days, I have been sick with fever, today. Then I started chest injury, it is like a second and then leaves, encountered every 5 minutes or so, first I thought it was heartburn, and just took some Milanta until I describe my sistuation my father, he said that IT will no longer stay in t sounds like heartburn. This is a pain in the ear-piercing is different each time the pain is sometimes a little pain, and sometimes it hurt like a bitch. When I was in a cold, I did not eat much of the reason, I'm not hungry, can my body tells me to eat?
