Hey beast,
Well, this is something that I have struggled with as a reasonably still new third year. I think it is a hard thing to learn for some people, and maybe everyone does it differently. There are books like Schwarz' Physical Diagnosis which is really a great book, and then other pocket sort of books you can read through. I say read, because I found that it was sort of just a weird format that had to be memorized, burned into my brain.
The review of systems seems inherently awkward to do, but once you have memorized the huge list of stuff to ask, then it sort of comes out easier.
For me, the hard part was actually sitting down with a real, live patient and then going through my history and physcial. I felt awkward and fumbling, but as I say, you somehow do get better at it. For web sites, I thought UCSD site (
http://medicine.ucsd.edu/clinicalmed/links.html) was good and there is another at I think, Virginian Commonwealth? I just did a google search and browsed through the different sites. As for the weird, stilted language, welcome to medicine! That was very hard for me to learn but after a while you become more fluent in 'med-speak.'
