Symptoms
By Mayo Clinic staffReactive thrombocytosis rarely causes symptoms. More often, signs and symptoms relate to the underlying condition. If symptoms of reactive thrombocytosis do occur, they may include:
- Headache
- Dizziness or lightheadedness
- Chest pain
- Weakness
- Fainting
- Temporary vision changes
- Numbness or tingling of the hands and feet
When to see a doctor
Because thrombocytosis isn't likely to cause symptoms, you probably won't know you have the condition unless a routine blood test reveals a higher than normal number of platelets. If your blood test results show a high platelet count, your doctor will try to determine the reason.
