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
  • Atherosclerosis
  • Costochronditis
  • Angina
  • Mitral Valve Prolapse
  • 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:
high air pollution exposure
severe leg cramps caused by walking
male pattern hair loss
chest wall pain
history of angina
severe fatigue after slight exertion
high hydrogenated fat consumption
long-term sleep surplus
apple-shaped body when overweight
heart attack(s) in mother
small social support group size
having excess body fat
... 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
Arrhythmias 94% Confirm
Costochronditis 61% Possible
Heart Disease 30% Unlikely
Atherosclerosis 0% Ruled out
Mitral Valve Prolapse 0% Ruled out
Angina 0% Ruled out
* This is a simple example to illustrate the process
