Good Morning Realtor. It's the beginning of November and my symptoms persist. They're still about the same. Some days I feel fine and the symptoms are very mild while other days the SOB/air starvation is significantly noticeable. I still run 4x/week. 2-3 miles a day and lift weights 4x a week. O2 sats during the runs range from 95-99%. Sometimes during heavy exertion while lifting, O2 sats dip to 93-94%. I try and remain busy constantly moving. To date, according to the doctors, my lungs and heart are clear and normal. Last CXR in September as compared to a previous CT, was normal. I am getting another opinion from Johns Hopkins Pulmonary in January. I've made an appointment to see a GI and try to schedule an upper GI as I do suffer from acid reflux and regurgitation. Reflux can play a role in inflammation of the bronchial tube which often leads to SOB. Maybe it's as simple as monitoring my diet and making some dietary changes, I'm continuously looking for answers to date. Interestingly, it seems like my wife suffers from very similar symptoms as I do. Not sure what to make of that as of right now. Hope you're finding some level of relief.
