Unexplained chest pain?

Hi, I had exactly the same problem, so I went to my doctor and they did all the blood tests etc, nothing came back. Still I was having the problem, eventually my doctor arranged for me to have an endoscope. This showed that I had a hiatus hernia. I was put on medication, and touch wood along with the medication I take daily. I've had no more problems from it. This was 2 years ago.
