I have been using Apple Cider Vinegar to treat a wart and it seems to be working however the skin around it has turned black. I can't find anything about the vinegar or warts that should cause this. Did I just put my bandage on too tight?
I don't want to visit the emergency room for nothing, but I am concerned because I have no idea what this is.
The acetic acid in the vinegar is burning the skin around the wart. You need to be careful to protect the skin and keep the vinegar on the wart. One way to protect the skin is to coat it with vaseline.
