Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose severe lower abdominal 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.
