Have been silently reading all of these stories for the past few days. I’m in shock about how many of your stories resemble mine. First, I quit smoking in March of 2012 after approximately 25 years of 3/4 packs per day. For the past 10 years I’ve experienced intermittent chest pains. I’ve had every non invasive cardiac test done and all came back normal. The diagnosis ended up being Costochondritis. In February of 2021, I tested positive for COVID. Symptoms were pretty mild only lasting 1-2 days. But I began experiencing intermittent SOB. They type of SOB where I can’t catch a satisfying deep breath that I starve for. Eventually it achieves the deep breath and it’s satisfied but only for a short period of time. At first, the SOB was sporadic. Every few days lasting for a day or two and then resolving and staying away for a week or longer but it always returned. In the summer of 2021, I was diagnosed with hypertension. All cardiac tests (CT w/contrast of the chest, ECHO, stress, Holter etc. etc.) were repeated and all tests were found to be normal. No plaques or blockages by CT. The SOB continues and became more frequent. In November of 2021, I saw a Pulmonologist. Pulmonary Function Tests were performed and I was cleared for COPD and any lung disease. SOB improved slightly for a period of time. In February of 2022, I tested positive for COVID AGAIN. This time the virus seemed to get into my lungs as I had a respiratory infection for about a week or so. It took a couple weeks for it to totally clear but the SOB returned much more frequently. In May of 2022, I saw a different Pulmonology group in a different city. He ordered PFT and sleep apnea study. As of the of morning June 22,2022 I’ve was cleared of COPD, any interstitial lung disease and sleep apnea by two different pulmonogy groups. All values were between 102-106% of the expected in the PFT tests. Further, my yearly ECHO done in early June was normal. So where do I stand?!?!? I have pretty consistent SOB, starving for air, excessive yawning. No cough, little to no sputum or phlegm, under control BP and heart rate. I try and run 4 miles 3-4 nights a week and w/o any issues. I lift weights 4-5x a week w/o any issues although the SOB, sigh breath, air hunger issue still remains. The NOT KNOWING is really bothering me. Anxiety?!? I’m taking Buspirone. GERD?!? I've gone from Nexium to Protonix now trying Rabeprazole. My GP, whom I saw a week ago, couldn't identify anything from a regular visit and physical examination. He believes its GERD and suggested changing to Rabeprazole. I’m at a loss. I’m 5’9 and weigh 210 lbs. I’m a pretty muscular guy with some extra weight. Could it be I need to lose a few pounds?!? Diaphragm issue?!? I woke this morning checked my BP and O2 sat. BP was 111/75 and initially the O2 sat was 93%. It increased within 20-30 seconds to 98%. I'm still having SOB and now its accompanied by sharpish pain on the right side during inhalation. I go back to the GP in a month. I think I'm going to request a CT or CXR. Further, I've made an appointment with Johns Hopkins pulmonary.
