Frequency Of Rashes

What Causes Recurring Rash?

Recurring rash can have various causes, ranging in severity from 'minor' to 'critical'.  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 rash, 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 rash" as a symptom.  Here are eight of many possibilities (more below):
  • Electrical Hypersensitivity
  • Vitamin C Need
  • Low Carbohydrate Diet Consequences
  • Epstein-Barr Virus
  • Infectious Mononucleosis
  • West Nile Virus
  • Lupus (SLE)
  • CLL Leukemia

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:
short-term memory failure
major inflamed cuticles
severe emotional instability
constant fatigue
regular infections
itchy skin
fatigue for over 3 months
facial burning/tingling
short-term low-carb dieting
having a slight fever
mild abdominal discomfort
painful cervical nodes
... 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 rash:
Cause Probability Status
Lupus (SLE) 94% Confirm
Electrical Hypersensitivity 19% Unlikely
West Nile Virus 14% Unlikely
CLL Leukemia 3% Ruled out
Infectious Mononucleosis 3% Ruled out
Epstein-Barr Virus 3% Ruled out
Low Carbohydrate Diet Consequences 0% Ruled out
Vitamin C Need 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 Skin Conditions section of the questionnaire, The Analyst™ will ask the following question about frequency of rashes:
Do you tend to get rashes?
Possible responses:
→ It is not a problem for me / don't know
→ Generally not, but I do have a rash now
→ Occasional (several times a year) moderate rash
→ Frequent moderate rash / occasional severe
→ Frequent (several times a month) severe rash
Based on your response to this question, which may indicate unusual current rash, occasional rashes, regular rashes or frequent rashes, The Analyst™ will consider possibilities such as:
Effects of a Low Carbohydrate Diet

The May 2004 Annals of Internal Medicine study showed that most of the Atkins Dieters had significantly more rashes than the general population.

Lupus, SLE (Systemic Lupus Erythromatosis)

Skin rashes are reported by 74% of lupus sufferers.


Skin lesions and rashes – tender reddish bumps or patches on the skin – are common.

Vitamin C Requirement

Scurvy has rash as one of its symptoms.

West Nile Virus

A rash is present in 20-50% of patients.
