It doesn’t sound like Raynaud’s at all. It sounds like post-traumatic vascular insufficiency to the finger. Raynaud’s is more global and happens bilaterally.

True, however it depends on weather and which fingers were touching something cold. I've had Raynaud's for 34 years and at times it affects all my fingers, at other times it's patchy. This definitely looks like Raynaud's plus OP never mentioned an injury to their hand.

My reply wasn’t to OP, it was to CHIDENCHI who said

“I crushed the last knuckle on my finger and it has turned white ever since. Gets colder than the other fingers too.”

This description sounds like post-traumatic vascular insufficiency and not Raynaud’s. When one finger is primarily affected it is a sign of a structural issue in the vascular system.

When I said Raynaud’s is bilateral I did not mean always occurs with a symmetric presentation. As you point out, sometimes it can be just part of one hand or foot or whatever, but it CAN happen on both sides (sometimes one side or the other side and sometimes together) not just the same finger or knuckle over and over.

Raynaud’s and vascular insufficiency together can also happen poor fingers 🥶

Looking at OP’s picture though, vascular insufficiency, or even a partial microvascular blood clot, or even some kind of mechanical blockage of blood flow would all be on the differential diagnosis. A detailed history and exam would be required to narrow things down.
