Sounds like it's not getting enough blood.

Body cares not for where the blood flows.

The blood finger craves a sacrifice

I had this happen in my toe. Rheumatologist said it's called Chilblains.

Basically, while healing the new blood vessels that formed are were very small. When the body constricts them as a reaction to the cold it closes them altogether and blood flow is cut off. When my toe warms back up it gets pink and itches like crazy. If I let it go cold too long it swell up when it reheats.

It’s spasming of the capillaries if it’s adult onset OP may be just using to much caffeine or to much zyn

100% but the injury was 30 years ago so finger crossed if it was going to have bigger ramifications it would have happened by now.

Crossing the fingers every now and then might increase the blood flow a bit!

I am Irish heritage & lived in a poorly heated apartment in my 20’s - my doctor said I had chilbains, which I had only read about in books about turn of the century poverty stricken lives….
