Well, funny you mention that. Today I waited on a lady who has Raynaud's.
No. I don't have Raynaud's. Right now, my nose is fine, but WHEN it does suddenly get freezing cold - it will STAY that way and I can't get it warm - and it's UNCOMFORTABLE!
Ha! I finally got this idea to take my headband/ear warmers at bedtime and put that around my head the other way, so that it covers my nose so I can sleep.
