OP, this is an indication that the tissue has died and has become necrotic. This tissue needs to be removed urgently. I am very concerned that an infection of this tissue could become systemic and fatal, potentially in hours.This is a definite indication to immediately head to an emergency room.I am so sorry you are going through this, but you need to be admitted and likely get surgery so that this does not become immediately life threatening.PLEASE DO NOT WAIT UNTIL YOUR APPOINTMENT IN AM
If one of your fingers is squishy, you need to go have it looked at immediately. If you have gangrene again it can kill you if left untreated. Im just so sorry you are going through this.So when is a black finger just Raynaud's and when is it gangrene? The right index finger isn't squishy, but the skin is breaking down and it's oozing something smelly.
