Chest pain

During Friday afternoon morning tea break, suddenly my chest is so painful that I find it difficult to continue working. I nearly wanted to tell my manager that, but it stop after one minute or so. This has already occurred ever since after I had my spine operation. I didn't tell my mother and I didn't plan to tell her too. If I tell her, she will say too heaty and I always eat junk food. So I only tell my father, he said go see doctor. Well, I hope it's nothing big just that the weather is very hot.
