these q's normally go in the user photos section, but based on the photo, yes, about a 3/10, which is bad enough. gyne that's been around for more than a year or two can only be fixed with an op. make sure you get an experienced plastic/cosmetic surgeon who's done a lot of these, not just some general surgeon who'll carve you up anywhere and leave you irregular and uneven, there are specific techniques for this. i assume oz has some form of board certification for ps's. if you check out the find a surgeon in your area part of the boards or use the site search engine you should find good past discussions on people probably in different states.
you also don't want to do just lipo if the gland tissue component is dense enough to leave a lot behind, but an experienced ps would know enough to keep the excision option seriously open, and i would bet in your case he should.
when in november? talk it over with your ps, but you'd probably want 3-4 weeks recovery to be safe, you don't want to screw it up a fix meant for the rest of your life for the sake of just one trip.
sorry for the bad news, welcome to the club, at least it can be fixed.
