Hardly know where to begin! Diagnosis ET at 87ish…put on hydrox immediately with platelets # checked every two months. Number varies anywhere between high 400s and as high as 750-800 depending on amount of hydrox involved! The more hydrox the lower platelets BUT higher hydrox very much results in lower red blood = big time lack of energy! What to do? Yes, I’ll be 91 Sept! All I want to do is rest…. Now on only 500mg daily hydrox effort to raise red blood to acceptable level. Had been on 1500md daily.
