A quick synopsis of my situation… In late 2020 I felt a minor dizziness and my balance was a bit off… Also had loss of appetite… I was thinking at that time that maybe something was wrong with my brain… I was also forgetting things short term which I never did before.. Went in to the Dr for tests… CBC indicated potential problem.. HCT was very high.. Also saw a neurologist who ordered a brain scan… Saw hematologist who ordered JAK2 mutation test.. JAK2 test confirmed I had PV.. As a “bonus”, neurologist said I had physical evidence of a stroke.. They couldn’t tell me when, just that I had one… I couldn’t believe what was happening.. I keep active , bike ride almost every day, plenty of walking, etc.. I asked neurologist..how could I have possibly missed a stroke?? She couldn’t give me a good answer except to say that normally this would have had major symptoms… I am lucky in that I feel really good, bike any day the weather is reasonable… Hydroxy-urea has my HCT under control.. No pain, good energy level, and short term memory has improved.. Best to you..
