I still cannot make myself warm enough. This is especially true for hands and feet. It turns out that I have very low ferritin which can produce this effect. Very low ferritin can cause extreme fatigue, too. Maybe this is exacerbating my symptoms.
The nurse from the hematology office wrote to me with suggestions. I am going to eat dried fruit and raisins. I do not like seafood, so that suggestion is not implementable. I already eat beans, meat, and leafy greens.
