And I'm tired of it and I can't get warm. Is this a PN thing, anemia, or possibly something else?

I have shoes AND socks on, pants, long sleeve shirt. Sitting in front of space heater, outside air temp 52, maybe 68ish in house.

My skin is cold to touch, feet feel like ice blocks. Hands ok.

CBC 2 weeks ago unremarkable.

Ideas/suggestions?
