Welcome, @jerrel, though I see you’ve been a member for several years but this is your first time posting! ☺️ I’m glad you recovered so quickly from your stroke. I’m sure the physical therapy took perseverance on your part but it paid off.
Having phlebotomies regularly to keep elevated hematocrit lower with PV can affect your iron and electrolytes. Thank you for sharing what has helped to keep your levels somewhat back to normal…though not quite. It looks like your doctor is considering iron infusions to help with the depletion. We do have other members who have iron infusions after phlebotomies. A few have talked mentioned their how the infusions have worked for them in this discussion

Does your hematologist oncologist feel that your PV may have been the cause of your stroke?
