<s>[INST] when i woke up this afternoon, i work nights, my chest was hurting on the center left side...well I have been awake for about 4 hours now and the pain is still on and off hurting. When it is not a stabbing pain it is a low achey pain. I am 24 years old, I am a bit overweight,I am 5"9  and 240 pounds.  and I have suffered from anxiety.My heart rate is also very fast. I have suffered from high blood pressure but am not taking anything for it right now. This has happened before but it only lasted about an hour, this time is has persisted. Emotional stress seems to cause the pain to last longer it seems. what should i do? [/INST] There are two entities in cardiac sciences!)
