Why does waking up early or working late give me chest pains? - chest pains more condition_symptoms

I experienced chest pain for several years. There are a lot of pain, then nothing else really boring.

Recently, I had 6 months free to return the package and after a few weeks, the pain disappeared.

Now I'm working again and again, the pain returned. To quit, especially if, sooner or later.
I have been in more than one doctor and say that my heart is right. I'm not on the weight, my work and life stress enough.
What is fever?
