Hot drinks, carbs (glucose tablets if you manage these), soup. Wrap up. Head, hands and feet warm. Sleep maybe or gentle massage to get the circulation moving.
Unfortuantely when I used to get that symptom, nothing like that helped, the heat from surface heat was like it couldnt penetrate into my body.
I still have times where I cant warm my feet or hands up without putting them into hot water (wrapping up doesnt help, I need an an actal external heat source) but I dont get anything like what I used to get with this where I couldnt warm anything up at all.
I used to spend a lot of time sitting on a heater trying to get warm and would be left bright pink due to the heat (almost burnt my skin) but would still be cold.
It must be something going wrong with the the part of our bodies which actually sense temperature. **that's making me wonder what part of our body does that? other then the obvious our brains** I had at least one incident in which I burnt myself with hot water coming out of a tap but I didnt feel it (I also burnt myself on my oven and blistered my skin and didnt feel that either at the time).

Min if it is any consulation to you, after at least a few years of that icey cold thing. .. I ended up swinging the other way and instead then had issues with feeling too hot.. eg having too hot feet and having to sleep with the hanging out the bed. Over heating suddenly during the night even on not so warm nights. Interestingly my hands which used to feel very cold to others and probably had felt cold to others all my life, nowdays usually are always warm.
Now I dont get that hardly much either at all (just some nights when Ive over done I suddenly get too hot and gone back to night sweats due to this). Ive had times when Ive slept in a bath of cold water..and feeling like my body was heating the water.
Our bodies are so screwed up. Sooner or later that symptom may well shift to another.
Autonomic system dysfunction symptom?????? That regulates the body, maybe it regulates how we precieve temperature? does anyone know?
