What Causes Cold Sores?
Cold sores can have various causes, ranging in severity from 'worrying' to 'serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose cold sores, 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 "cold sores" as a symptom. Here are three possibilities:
- Herpes Simplex Type I
- Mercury Toxicity
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:
physical punishment during childhood
somewhat disturbed sleep
dizziness when standing up
short-term memory failure
difficulty getting out of bed
long work hours
refined sugar consumption
regular sore throats
heavily coated tongue
often/always feeling unusually cold
... and more than 70 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of cold sores:
|Herpes Simplex Type I
