I am experiencing difficulty in breathing-slow and irregular. i have reflux, ct scan shows minimal peripheral fibrotic changes. ?

Incomplete workup: You should see a Pulmonologist (lung doctor) for a systematic workup, rather than relying on a CT scan. The fibrotic changes may or may not have anything to do with your symptoms - a good lung doctor can determine if so. You may need a bronchoscopy &or pulmonary function tests (see how fast & deep you can breathe). Are you a smoker? miner? asthmatic? Use HealthTap Prime if you have more questions.
