Have no worries, Indy Med.
Most of the people that are hanging around these forums are overachievers 😉, myself not included, I am actually an underachiever 🙂 But that's not a bad thing, it just means I am capable of even more than the good amount I have done!
At any rate, General Surgery is becoming more and more in demand these days, contrary to what people are going to tell you. And aside from board scores, which are only 1 of the 3 things you'll really be evaluated on, your performance in rotations is the most important.
What you need to do, if you havent already, is do A LOT of 4th year Sub internships in surgery and really get in with a bunch of docs. The best way to guage your performance in a surgical rotation is if you're making your Attendings' lives easier. And the more you do for them without them asking, the more they'll take your side when it comes time to pop the question (that is, asking for a recommendation, of course).
From what I hear, there is an EXCESSIVE availability of General Surgery Internships available, contrary to popular belief, and the paranoia that a lot of people on here will have you believe. You made it into med-school. And the old addage is certainly true, that that was the toughest part of medical school, and your career in general. If you go out there and really promote yourself properly, you'll get that Gen Surge Residency you want without that beautiful board score. Board scores are only skin deep... And anyone in surgery will tell you, it's better to be lucky than good... sometimes...
