This is recurring after trauma to the vagina such as niks from shaving or most recently wiping too hard. Sore does not itch nor hurt when sitting but does burn when urinating. There have never been any bumps or pustules and sores disappear within a week or so.
Similar picture was shown to OBGYN previously when sore was not present and OBGYN was unconcerned and did not suggest any further testing. She believed it was a scratch from shaving and advised to change blades more often.
