As of late, I often wonder if my replacement was truly necessary...I didn't get a 2nd opinion etc....so with all the misery I'm left with, I wonder this now. IN all these surgeries listed hip and knee replacements are two of some unnecessary ones. Talking to my acupuncturist today and we got on the MD subject and he is old enough to remember the MD's that made house calls, I sure do and then he went on with the history of the doctors and pharma post 1960......and how Profit Driven it all is today...keep the stockholders happy...sad but true.... I like progress but things are out of control as I see it. Doctors forming corporations, etc. ugh.... Anway, here is one site, and there are others on this same subject: articles.mercola.com/sites/articles/.../07/.../unnecessary-surgeries.aspxCachedSimilar Jul 10, 2013 ... If your doctor recommends any of these unnecessary surgeries, please be sure to get a second opinion.
