good answers. hugs to all Frank

Thanks to all for replying. So it's as I thought. Just a thought: I'm not as conscious of the cold when I'm up and walking around -- which probably means my circulation is working. So far no blue nails!

When my feet get cold, my whole body gets cold!

It may mean poor circulation. Your toe nails will turn blue if you're not getting enough oxygen. Then next your finger nails.

@A MyCOPDTeam Member It's a matter of "poor" circulation. By example: when I smoke, my hands and feet are cold ; when I quit smoking, hands and feet are becoming warm (and happy). Also, as we age, circulation is also ageing. Hugs
