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.

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
Why wouldnt you suspect infectious disease? Could there be local infectious disease or insect/animal bites that are common? In California we have Valley Fever which is not know outside of certain areas. Could a local infectious agent not well known be an avenue to look down? Some resistant bacteria?
Theres no infection Im aware of that causes your fingers and toes to necrose. The only way that happens from an infection is when someone is in septic shock and the vaso pressors they need to stay alive cause their small vessels to spasm shut
