Hey there Mehul,
I met you at the NRH pain fellowship interview.
Thanks for the recommendations. I think Wall and Melzack (pub 2006) is a great textbook for very detailed and very up to date information/reference, and is less useful as a clinical companion. RE: Wall and Melzack's handbook...not as practical as I would like. Plus, it was published in 2003.
Bonica's very comprehensive but out of date at this time (published 2001) compared to Melzack's.
The Warfield/Bajwa text, published 2004, is good, and right now you can find them online for $15 shipped! Look at abebooks.com
My favorite right now for practical clinical info is "Essentials of Pain Medicine and Regional Anesthesia" by Benzon/Raja/Malloy/Liu/Fishman published 2005. Although I'm a little pissed I'm recommending a book edited by Benzon, who runs a pain fellowship that refuses to take applications from non-anesthesiologists. He'll be forced to change come July 2007 when the new ACGME guidelines come into play.
Weiner's pain managment published 2006 is huge, covers a large range of esoteric topics "Aromatherapy for pain relief" "Magnetic Therapy". I have not fully reviewed it yet...
One book I really like right now is Decision Making in Pain Management by Ramamurthy. Not a textbook, more of a clinical companion. Gives an algorithmic approach to common pain issues. While I understand the dogmatic pitfals of clinical algorithms, it is nice to have as a new pain fellow to get a handle on things.
I really like Waldman's atlases of Common and Uncommon pain syndroms.
Are you all aware of MD Consult's Pain Managment service? $10/month gets you online pain textbooks and full text of the major pain journals. An AWESOME deal! Check it out.
