Title: Cheaper than the ER!
Review: I bought the two volume set several years ago. It paid for itself the first time I used it and was able to get a severe headache under control at home, instead of going to the emergency room. Yes, even with a killer headache or back spasm, the book is easy to use, although it's got enough technical detail to make it an essential reference in any physician's library.
