With your levels as they are you need to act sooner rather than later, you must feel terrible. The thoughts of being in hospital at christmas arnt good, but if i was you id be going for the transfusion asap.
A hematologist/oncologist is a doctor who specialises in blood disorders and cancers (which alarms a lot of people - just think obs and gyne two different things treated by the same doctor - if that makes sense). Do you you know why your so anemic?
Good luck to you, and hope you get things sorted out, keep us informed of your progress.
Best wishes,
Linds
