Can you help me figure out my PFT report? I've been told I have allergic bronchitis. My x-ray and sputum culture look normal, and I used to smoke but quit. Right now, I'm mainly dealing with throat irritation, coughing, and nasal congestion, but no fever or trouble breathing. What can I do to keep these symptoms from coming back? I'm using kastilex ab tablets and furamist spray. Any advice would be great!
