This has recently become a problem for me. I have had PV for seven years now and am 74 so feel lucky to be alive, and enjoying life. I walk regularly but am often breathless and struggle with uphill walking now. Not sure if it is winter related. I am also having to cope with more itching, (definitely winter-related), especially at night which interrupts my sleep pattern. I take Atarax before bed, or Zyrtec and Zantac if it is not too bad and am going for UV (sun bed) treatments, 15mins a week for 10 sessions. I am on Hydrea, have been for some years now, and have not needed phlebotomy for a couple of years, although the haematocrit remains steady (between 40 and 45%). I am not sure whether I should just adapt to how I feel and concentrate on walking exercise, or whether I should push myself to do more. I am recruiting my reluctant husband to help with housework and shopping, which I feel is necessary if I am to continue coping. Any thoughts?
