Severity Of Unexplained Recurring Fevers

What Causes Recurring Fever?

Recurring fever can have various causes, ranging in severity from 'needs attention' to 'generally fatal'.  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 recurring fever, 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 "recurring fever" as a symptom.  Here are eight of many possibilities (more below):
  • Hepatitis
  • Ehrlichiosis
  • Babesiosis
  • Lupus (SLE)
  • Kidney Stones
  • Diverticular Disease
  • Lyme Disease
  • Valley Fever (Coccidioidomycosis)

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:
Lyme disease
non-vaginal candidiasis
shortness of breath when at rest
disseminated coccidioidomycosis
regular sore throats
painful axillary nodes
history of kidney stones
reduced sense of taste
severe right lumbar pain
mild abdominal discomfort
recurring depression
history of shingles
... and more than 80 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of recurring fever:
Cause Probability Status
Lupus (SLE) 95% Confirm
Babesiosis 27% Unlikely
Valley Fever (Coccidioidomycosis) 17% Unlikely
Kidney Stones 3% Ruled out
Diverticular Disease 2% Ruled out
Hepatitis 1% Ruled out
Lyme Disease 1% Ruled out
Ehrlichiosis 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Metabolic Symptoms section of the questionnaire, The Analyst™ will ask the following question about severity of unexplained recurring fevers:
If you suffer from unexplained recurring fever, how would you rate its average severity?
Possible responses:
→ Not applicable / don't know
→ Very mild, almost nothing
→ Mild - I can function normally with it
→ High - I can function but I would rather be in bed
→ Very high - I'm bedridden
Based on your response to this question, which may indicate mild unexplained fevers, moderate unexplained fevers, unexplained high fevers or unexplained fevers that hit hard, The Analyst™ will consider possibilities such as:
Lupus, SLE (Systemic Lupus Erythromatosis)

Fever of more than 100F (38C) is reported by 90% of lupus patients.
