I have had Essential Thrombocythaemia for over 3 years which has been controlled by Hydroxicarbonide. I have just been diagnosed with Acute Myeloid Leukaemia. I see the haematologist next week to talk about treatment, but in the meantime I have had my Hydroxy doubled. I have a feeling it has increased my tiredness and I get a lot of pain in my chest. Does anyone else have this problem? I am 77 and have been told I am too old for aggressive chemotherapy in hospital.
