I have been diagnosed with several different things over the many years of this illness. Most recently, the diagnosis is cough variant asthma and moderate COPD. I just completed an allergy panel and the only thing I am allergic to is feathers. For pete’s sake! Feathers! I don’t have any exposure to feathers at all (pillows or bedding, no birds). How is this test result relevant to my diagnosis?
