Raynaud's Phenomenon

What Causes Raynaud's Phenomenon?

To successfully treat and prevent recurrence of Raynaud's phenomenon we need to understand and — if possible — remove the underlying causes and risk factors.  We need to ask: "What else is going on inside the body that might allow Raynaud's phenomenon to develop?"

  • learn what you should be doing right now
  • have a doctor review your case (optional)

Accurate diagnosis of the factors behind Raynaud's phenomenon consists of three steps:

Step 1: List the Possible Causative Factors

Identify all disease conditions, lifestyle choices and environmental risk factors that can lead to Raynaud's phenomenon.  Here are five possibilities:
  • Lupus (SLE)
  • Silicone Disease
  • Multiple Chemical Sensitivity
  • Dermatomyositis
  • Chronic Fatigue-Fibromyalgia

Step 2: Build a Symptom Checklist

Identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
seizures
shortness of breath when at rest
severe non-specific arm pain
variable duration morning stiffness
joint pain/swelling/stiffness
chronic fatigue in family members
inflamed cuticles
frequent sore throats
frequent unexplained fevers
morning stiffness lasting hours
unsound sleep
mouth sores
... 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 Raynaud's phenomenon:
Cause Probability Status
Chronic Fatigue-Fibromyalgia 98% Confirm
Lupus (SLE) 18% Unlikely
Dermatomyositis 5% Ruled out
Multiple Chemical Sensitivity 3% Ruled out
Silicone Disease 0% Ruled out
* This is a simple example to illustrate the process
