Contact Palliative Care. They are wonderful and will look at you holistically. Your oncologist only cares about treating your cancer.
I have been in remission for 15 months and still have extreme weakness, tiredness and difficulty walking up stairs. My Oncologist informed me that my red blood count was very low. She has started me on B12 injections and IV hydration, but these treatments only work for a few days. It is very frustrating to be told you are in remission, and yet, feel no better. Have you had recent blood work? Keep me posted on your situation. I also take Adderall for energy, but, again, only helps a little. So sorry for your frustrating situation
