One cold finger?

Cc

Is this concerning? Normal? I don’t know when it started (maybe a couple of years ago?) but I’m noticing it a lot more now just because it’s colder and I’m going out more. It’s just this one finger that stays cold when I get inside and goes a little numb. It takes maybe five minutes to go away. This was today when it was about 20F out (so actually warmer than usual lol) anyone else have this?
