I'm curious about sub-specialty fellowships and what the lifestyle is like. Basically, I'm wondering what the going salary is, as well as what the time committment and levels of responsibility are. I know this will vary a lot between fellowships, but can you tell me if it is basically like residency all over again, or more like being out of residency? I don't know exactly what specialty I'm thinking about (and it's kind of early for me still), but how about pediatric surgery or REI as examples (or whatever you know about). Thanks!
