MedHelp doesn't allow pics of genitals on the site, so don't post it directly here, like on your profile or anything.
Also, we can't diagnose as we aren't doctors, and most things require lab tests, physical exams, etc. We can give you ideas. If you haven't been diagnosed with yeast, you should get this checked by a doctor and stop that treatment. It doesn't sound like an STD, and may well be from yeast, but you really should get it checked out.
Can you attach a photo or a link such as imgur?
