I know of a person, who was misdiagnosed for over fifeteen years, the ailment was a bad back, after severe pain sent her for a different opinion, the diagnosis was Gall bladder problems. It took less then fifetten minutes for the doctor to figure this out, a later ultrasound confimed gallstones. The same Doctor, also misdiagnosed another person with Parkinsons, looking for another opinion, was eventually diagnosed with Luekemia, unfortunatly, not in time to save the life of this person. They had been hospitalized a bit later and given several months to live. The Doctors had to change that to about a week, and that's about what it was. I think that years and years of schooling only make a differance if the doctor cares about thier Patients, this one didn't, and I am certain, still doesn't. If you are not seeing some change or improvement in your condition, get a second opinion, it may save or prolong your life.
