Hello,
Did you say skier? Are you aware that being in high altitudes thickens your blood and can raise your blood counts? I was diagnosed with PV 13 months ago at age 56. Shocked can’t begin to describe hearing that but I too was always healthy and no daily meds
What so ever. It was a rough first year but now I have a pretty good routine. My point was anyone with certain blood disorders can not be in high altitudes due to it thickening your blood. My friend had high blood counts and the doctor was doing all kinds of tests and then she revealed she was a skier and that was what caused it. You did say you have not skied this year so this is a long shot but something you should definitely speak to your doctor about. Good luck!
