In January 2014, Stacy developed a lingering cough. By June, it had morphed into a hacking cough that would not cease. Something wasnt right. Over a six-month span, Stacy went to her primary-care physician three times. On the first visit, the doctor gave her an X-ray, diagnosed her with walking pneumonia, and prescribed antibiotics. On her second visit, the doctor remained convinced that it was walking pneumonia. And on her third visit, she was still not better, so the doctor ramped her up to a higher dosage of antibiotics.
