Perhaps she was being poisoned or had an immune problem? He sent her to an immunologist, a basic check revealed nothing. He sent her back to the cardiologist who said that she had seen the best doctors in town. They didn’t know what was wrong with her so therefore there was nothing wrong with her.
Finally she went to see a doctor elsewhere: an unusual type – a curious polymath. He suggested a rare immunological condition. The first set of doctors dismissed the diagnosis although they hadn’t done the relevant test. She’s now under the care of the immunologist who hasn’t agreed with the diagnosis and only manages the patients problems on the basis of symptoms. To deny ignorance is to deny the possibility of progress.
