Kinda... But I figure that medicine and surgery are different enough that you'd know one way or the other.
With applications to IM, Peds, and GS... youve pretty much got all of medicine covered. If you feel like you miss surgery, but are doubting your interest in it... then what are you "missing"? People have very different experiences in their rotations - good, bad, or indifferent. Are you basing your interest in a particular field on something that had more to do with your specific situation/experience in a rotation, rather than the specialty itself? Did you, for example, get to do a lot of hands on stuff in surgery... and now you miss the hands on stuff... but you dont want to sign your life away.
For example, everyone talks about how they cant stand IM rounds, and many dont care for long term management, myself included. On my IM rotation, rounds were unusually short and painless, and there was an almost entirely inpatient focus. So, I wonder if I'll still like IM, when in residency, I run into the things I don't really like, and havent actually had to deal with for an extended period of time yet. Point is, In my own case, I dont want to base my choice on an atypical experience.
Enough about me, back to you... Think about what you like, what you dont, what you cant work without, and what you refuse to work with. So maybe theres a solution. Will you be satisfied if you do fellowship with a lot of procedeures (GI, cards)? Again, think about what draws you to surgery, and see if you can get that elsewhere.
