im similar cold feet to touch and can feel the cold, tingling and pretty sensitive and can be warm after a lot of walking mostly on soles and toes.
I have dropped by blood sugars alot over last 8 weeks and took a few supplements like r alpha lopoic b complexs and cartinine which got rid of the tingling and odd feelings.
Still a bit sensitive and left with pretty constantly cold feet but hoping that will clear up to as i get used to more stable blood sugar levels and i leave my 1000 a day cal diet im just about to finish.
It is worrying though, i have been podiatrist twice in few weeks for circulation and sensation tests and they say fine so it like whats going on. having flat feet not helping either. Hope it clears up as i feel good apart from that.
