Recently my left index finger has been going white and numb. It comes on slowly but returns to normal quite quickly once I have taken steps to warm it up. However, the initial onset isn't always related to being cold. It started happening occasionally about a month ago but for the past week it's happened a couple of times a day. Managed to capture a photo quickly one time as it was getting back to normal.
It isn't painful, but I am not sure what is causing it & Googling is not helping because it's only one finger - Reynauds phenomenon seems to always affect at least a few fingers. I am also confused because it happens indoors a lot and isn't triggered by cold.
I don't particularly want to waste a GP's time as it's not painful and resolves quickly, but I would be interested in hearing from anyone who definitely has reynauds to see if the one finger thing is unusual!
