Hello sir, Just wanting to now if apple cider vinegar is a healing med for a not sure how to spell it ,but it a skin dessert on my back I have for many years and it seems like I get it back in winter, as in summer I don!t have it, but it starts with a little red pimple, starts to itch and then ends up a sore and is fairly deal in the skin,and then leaves a deep scare on the back. I had it cut out a few times from Specialist And the last one I talked to here said that it was do to conpat ion and she told me to stop out my tongue, and then said I was seaping for that.it starts down my spine
