g. sinus CT scan, chest CT scan, phlegm cultures, blood work, pulmonary/respiratory tests, allergy
tests, tests for immunological disorders, but nothing shows up. It's all negative. I have taken allergy drugs, zertac and singular, Amoxicillian, nose rinses for sinuses, asthamex, proair, use of nebulizer and duoneb med's, and med's for cystic fibrosis, and nothing works. The Amox worked for a very short while than stopped working.
