Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose sore tongue, 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 "sore tongue" as a symptom.  Here are three possibilities:
  • Vitamin B12 Need
  • Iron Need
  • Vitamin B6 Need

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:
having had a small bowel resection
vegan diet
loss of appetite
water retention before menstruation
H2-blocker antacid use
reduced sense of taste
B12 deficiency
medium-term vegan diet
slight tongue swelling
shortness of breath when at rest
macrocytic red cells
history of carpal tunnel syndrome
... and more than 30 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of sore tongue:
Cause Probability Status
Iron Need 97% Confirm
Vitamin B6 Need 24% Unlikely
Vitamin B12 Need 1% Ruled out
* This is a simple example to illustrate the process
