Polycythemia vera symptoms

Most symptoms of polycythemia result from the increased blood viscosity and tend to disappear when the hypercellularity is managed. They include:
1) Headache, dizziness, vertigo and tinnitus

They are nervous symptoms due to decreased oxygen delivery to the brain and the ears. Tinnitus is a buzzing sound in your ears that doesn’t stop and can vary from being unnoticeable to causing severe discomfort.
