I have been diagnosed with this.
My specialist puts it down to cytotoxic drugs used for treatment of blood disorders.
I had AML then got essential thrombo Cytosis.
Iwas given hydrea and he seems to think it has caused my condition.
However i was also given busulphin to kill my bone marrow pre having a bmt.
I simply dont know what to believe.
I now feel tired and fine exertion comes very easy.
No way could i try any decent airobic exercise
