Signs and Symptoms

Polycythemia vera (PV) develops slowly, and it may not cause symptoms for many years. The condition is often diagnosed during a routine blood test before severe symptoms occur. 

Symptoms may include:

  • Itchy skin, called “pruritus,” especially after warm baths or showers
  • Headaches
  • Excessive sweating
  • Blurred vision, double vision, or seeing dark or blind spots that come and go
  • Ringing in the ears
  • Fatigue 
  • Shortness of breath
  • Weakness
  • Dizziness
  • Excessive bleeding or bruising
  • Reddened skin 
  • Numbness, tingling or burning sensation in the feet 
  • Feeling of fullness or bloating in the left upper abdomen due to an enlarged spleen
  • Weight loss for no known reason
  • Painful inflammation in the joints caused by gout
