text: You have to go see a doctor. No-one can help you on this list. We're all just guessing what might be wrong, and in any case we can't prescribe a cream or course of treatment - you have to see a doctor. It's unlikely you will be able to use anything you can just buy in a drug store.\n\nDoctors have seen all kinds of things in their seven years of training, and then every day since then. Believe me, they won't care what you've been doing, they are not going to criticise you, and you need to get this taken care of professionally.
