Ah some fellow cold people...!
I've been utterly 'freezing' all day, I honestly feel like an ice block. I whacked the heating up, and have been sitting (well laying) on the sofa with the kids watching films today under my slanket, with my toddler laying on top of me with her thick fleecy blanket on, AND furry boot slippers and socks. I'm still freezing.
For me it seems to be connected to pain & tiredness. If I'm in a lot of pain it feels as though my body just shuts down, and I get this cold, nothing warms me up, and I get so tired that I can't keep my eyes open physically. It's horrible. Had it for such a long time now, when I was a teenager and pre-diagnosis, the Dr's thought I had ME.
Just another one of those 'things' you have to deal with with no magical cure or pill!
Off to warm/fry the wheat bag...
