Undiagnosed

Hi there last year I was sent to Hematology where they told me I might have PV 

I had to do lots of bloods and sleep apnea test 

Jack 2 had come back clear but saying I have mild sleep apnea 

Today I went wasn't even in the room for 5 minutes where she said it's the haematrocit not haemoglobin that they look at 

And that's it's probably the sleep apnea and she don't think I've got anything 

But will have to have regular blood tests and if haematrocit is high then might have to have a bone marrow tests

I feel like I've been left with no real answers
