Can Applying Apalette Cider Vinegar On Vulva Cause A Chemical

Can applying apalette cider vinegar on vulva cause a chemical burn? I have been trying to get rid of an ingrown pimple down there and put acv down there for three days. The night I decided to stop was when I realized it became white, inflamed and burning. The next morning I woke up with what looked like cuts then that after winning took a hot bath and they look like sores. That was yesterday and they completely closedifferent up I just want to make sure it isn't anything bad
