I have a female friend, 36 years old, non-smoker. Her symptoms since March are coughing, shortness of breath, she wakes up dizzy and nauseated all the time. She has been on antibiotics, steroids, allergy meds, antacids, and currently being treated for mold toxicity. She has had x-rays and chest scans. She has been to the doctor at least a dozen times and nothing has helped. Any ideas what to be looking for?
