Did you know that 90 - 95% of a doctor's diagnosis will come from what you say? Yep! If you do not give the doctor all of your symptoms and history then you are asking him or her to diagnose you based on insufficient information. Whenever you go to the doctor, he or she will take a patient history using a mneumonic called, "OPPQRST." Every doctor on the planet follows this mneumonic. This translates into: Objective, Palliative, Provocative, Quality, Radiating, Subjective and Timing.
ONSET: When did it start?

PALLIATIVE: What relieves your symptoms?

PROVOCATIVE: What provokes your symptoms?

QUALITY: How would you describe the symptoms? Sharp? stabbing?, sore? uncomfortable? nausea? achy? throbbing? ripping? tearing?

RADIATING: Do the symptoms or pain radiate to another area of your body?

SEVERITY: On a scale of 1 - 10, how would you rate your pain or discomfort?

TIMING: How often do the symptoms occur?

Typically with chest pain, the additional LMN are added to the mneumonic which means: Last, Movement and Notable Symptoms.
LAST: When was the last episode?

MOVEMENT: What activities could you do before you first felt chest pain and what activities can you do now?

NOTABLE SYMPTOMS: What other symptoms do you have with your chest pain?
