Yeah that's a good question, and one I've thought about. Unfortunately all the other fields haven't been too appealing. As sad as it may sound, I think I will be one of those docs that doesn't claim to passionately like any one field, but likes a lot of them. I don't want to do primary care, i don't care for surgery's lifestyle, don't want derm or radiology, I do like GI but that's a 6 year total program and I don't like that either (although with fellowships for PM&R will end up being about the same length). PM&R seems to have a good lifestyle, no 3 yr IM residency, good pay, and... did i mention lifestyle? that's probably top on my list of factors to consider.
Anyway I'm not applying for it just yet, it's just a consideration that I 'discovered' lately so want to give it full thought.
Thanks again
