Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose upper-left arm, chest or neck pain, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "upper-left arm, chest or neck pain" as a symptom.  Here are six possibilities:
  • Arrhythmias
  • Angina
  • Mitral Valve Prolapse
  • Atherosclerosis
  • Costochronditis
  • Heart Disease

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
dizziness when standing up
acute abdominal pain
heart attack(s) in mother
having excess body fat
sleeping less than necessary
occasional chest tightness
heaviness of the legs
high air pollution exposure
fatigue after slight exertion
hiccups
undigested fat in stools
history of atherosclerosis
... and more than 50 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of upper-left arm, chest or neck pain:
Cause Probability Status
Mitral Valve Prolapse 90% Confirm
Costochronditis 60% Possible
Arrhythmias 22% Unlikely
Angina 2% Ruled out
Atherosclerosis 2% Ruled out
Heart Disease 0% Ruled out
* This is a simple example to illustrate the process
