Outside of vagina itches. skin looks dry and flaky around lips of vagina. no discharge, no odor and no bumps/sores is this an std?

Unlikely: But without being able to examine you and obtain a full history with knowledge of your sexual activities it is not possible to say with any degree of certainty. Go and see your pcp or a gynecologist and let them have a look at this.

Please bring this up with your Gynecologist who knows your medical history and can give you a through exam. If you don't have confidence in your Doctor see another for a second opinion.
