Much to my surprise, it has been great so far. Part of this is due to my team: my senior resident is full of boundless energy and good humor (she reminds me of one of my best friends, so much so that sometimes I forget that she's evaluating me), the interns on the team are super nice and easy to work with, and both of the attending physicians have been fair to work for and great teachers to boot. I've been learning a lot about how to handle patients independently, and the workload hasn't even been as much as I expected.
What I've really come to appreciate, however, is the actual intricacies of the work of internal medicine. Much of the cerebral exercise of medicine--exactly what makes it so frustrating to someone like me, who prefers action and pragmatic, instant solutions to the long-term waiting of medicine and diagnostics--the cerebral exercise of medicine is exactly what draws internists to their field. I found myself thinking about how I learned to play chess. I read through a set of rules in the chess box, played a few games against my father and uncles, and taught my brother how to play. I quickly tired of the game, though. The only way to be a true chess master is to have the ability to think thoroughly about consequences: one must be capable of anticipating how the move now will impact the board six turns later. In the same way, internal medicine is the chess of the medical field. By adding up the signs and symptoms and lab values that a patient has, the internist comes to a conclusion about what disease process is going on. She then makes a plan that not only addresses immediate concerns but anticipates problems down the road.
For example: a patient comes in from home with a pneumonia. The patient is ill enough to be hospitalized but not ill enough to require a ventilator or significant interventions. The internist makes sure to put the patient on appropriate antibiotic coverage, ensures that physical therapy is seeing the patient once it's clear that the patient is getting better, and when discharging the patient makes sure that he leaves with prescriptions for the right antibiotic as well as follow-up appointments with his regular doctor. She might also send him with a prescription for a probiotic supplement (to ward off C. difficile diarrhea, a condition for which one is more at risk after having taken antibiotics) or with instructions to have a lab drawn to check on his kidney function if the antibiotics given during the hospital stay are harmful to the kidneys. In all ways, the goal is not just to fix the immediate problem, but to look ahead and anticipate the next problem before it starts.
To put it another way, internal medicine seems to be the art of looking at butterflies and trying to see which ones will cause hurricanes and which ones will simply fly off to the next flower.
I suppose I've never been good at chess, though. I always wanted to be the kind of smart that can look six steps ahead and know what the best moves are as well as the most likely moves of my opponent; however, even when I was playing chess or Risk or other strategy games, I grew tired and frustrated with them quickly. I prefer the Zen approach of the surgeon: living in the present, dealing with what is in front of them, and approaching a problem with a concrete solution rather than a hypothetical or invisible one. I do not think this is a superior approach; it is simply a different one.
Some in medicine live in the present; they are the surgeons. Some live in the future; they are the internists, pediatricians, and family physicians. And some live in the past; they are perhaps the pathologists. They delve into what has already happened, students of the body's history in order to explain the body's present.
