The patient went back to her pulmonologist for a followup appointment after completing the medication treatment and was told by her pulmonologist that she was recovered. However, the patient continued to be symptomatic and expressed concern about her symptoms. The pulmonologist assured her that she was fine. Within the month, the patient began feeling weaker and experienced difficulty walking and sleeping. The patient then began coughing up blood and losing weight. She returned to the pulmonologist, who decided to do a lung bacterial culture. The culture came back positive for mycobacterium avium complex (MAC). He was referred to an infectious disease physician and treatment for the MAC commenced. In spite of multiple treatments, the patient ultimately required oxygen full time.
