You may be right that this is all related to your blood disorders. Having two blood conditions with the potential for blood clotting such PV with too many red blood cells and ET with elevated platelets bears a closer look and reevaluation.
I’m glad you went in to the ER…that set the ball rolling today to get you into your hematologist's office for a quick phlebotomy. Your red blood count must have been elevated.
Will you let me know what you find out Thursday with your next appointment? Was this your first phlebotomy?
