Merck: best investment on my lifetime.
This is one of the world's best medical books. I have been seeing more than a dozen of doctors and have spent over $200K in medical labs and radiology. None of them got the diagnosis. But finally, the Merck Manuel helps find the diagnosis. Everybody should have it on his bookshelf. If your doctors can?t help then just read carefully the chapters of this book that concerns your health problem.
