Hi, I was diagnosed with PV about a year ago. Have had four phlebotomies so far. I live in the US so I hope I am not intruding. Does everyone have to keep their Hemoglobin levels below 14? I am experiencing severe exhaustion. All I have read says I should take walks, exercise. I do not have the strength most days to walk. Depression is beginning to set in. You all sound so strong. I admire you. I was a Registered Nurse and am 76 years old. I find that nurses and doctors tend to look at worse case scenarios. Thank you for all your strength. It is heart warming to read your posts.
