A friend of mine is coughing up black mucus, has general malaise, pitting edema and has suffered from reoccurring bouts of bronchitis, pneumonia, fever and a persistent cough. She has been to see a pulmonologist, an ear throat and nose doctor and her primary care physician. They ran tests for fungal infections, had a bronch test, sputum culture, and blood cultures and has turned up nothing. She is 35 years old, an lpn, she is caucasian, he weighs about 160 lbs and is about 5 8 and the symptoms have been going on for four and a half months. Any ideas or advice?
