Hi, wondering what the cause of this sort of shriveling that is going on with these fingers? This doesn’t look like Raynaud’s Phenomenon, where we typically see red/white/blue fingers. These fingers (below) have some normal color, but seem shriveled in a manner inconsistent with them having been submerged in water (these lines are vertical as opposed to irregular/circular)
I have this going on with my hands and seems to be an overreaction to slight cold or stress. And I can rule out dehydration as well, as I drink 3 liters of water a day easily.
