For some reason, on my left hand I keep getting these green splotches appearing on the insides of my fingers, they don't wipe away leading me to believe their underneath the skin, they go away over the day but then come back in different spots/sizes the following day, I can't find anything about this on Google and it's really freaking me tf out, my hands aren't in pain or anything either so idk what tf is the cause, but my anxiety immediately makes me think it's something fatal or signs of something horrible.
