Essential Thrombocythemia Symptoms and Diagnosis

Essential thrombocythemia often does not cause early symptoms. It is sometimes found during a routine blood test called the complete blood count. The following symptoms may be caused by essential thrombocytopenia or by other conditions. A doctor should be consulted if any of these problems occur:

  • Headache
  • Burning or tingling in the hands or feet
  • Redness and warmth of the hands or feet
  • Vision or hearing problems

Platelets are sticky. When there are too many platelets, they may clump together and make it hard for the blood to flow. Clots may form in blood vessels, and there may also be increased bleeding. These can cause serious health problems such as stroke or heart attack.
