I've been having this really intense chest pain whenever I'm sleeping or after sitting down for a long time. It's weird because it never happens when I'm walking around. The pain doesn't spread to my jaw or arms, and I'm not experiencing any breathlessness, but my digestion isn't right either. This has been going on for about a month now, but only occasionally. Could you give me some advice on what's going on or what I should do?

Ecg and x-ray chest pa view and cardiac markers is advised to the patient.
