Hi, about twenty minutes ago I was sitting down eating dinner when I happened to notice that the knuckles on my left hand look rather funny. They almost look like they are bruised, but they don t hurt, tingle, and are not swollen. I have not been exposed to any extreme cold recently either. It s just my knuckles, and just on my left hand. Sort of a grayish color. Been looking online to see what others say, but can t seem to find anything that fits . It s not very severe looking, but still worrisome.
