I’ve read every word of this thread, as I have the many of these symptoms and frustrations. I wish no one else had to deal with this, but I appreciate that all of you posted, as I learned a lot from your words.

Here’s my story. I’ve been having “air hunger” for the past couple months, which has worsened greatly in the past 2 weeks. I never feel like I can take a deep breath, there’s immense pain in the center of my chest, and my heart rate/BPM via my Apple Watch fluctuates between 37 & 210 at rest. I’ve also fainted twice (out of nowhere) and feel dizzy when the breathlessness hits.

I’ve had 2 ER visits and an overnight stay at the hospital in the past week. The tests — focusing on pulmonary embolism, heart valve, congestive heart failure — came back negative. I have a premature bear, which they said isn’t uncommon. In fact, the cardiologist said my heart is really strong, which makes sense because I exercise a lot and have a healthy diet. I had diverticulitis 3 months ago on my right side, which is unusual — a sharp pain in that area next to my hip has lingered since then.

It seems like my symptoms kick into gear while eating and then linger most of the day. I easily did a bootcamp class 3 weeks ago and now have trouble walking my dog around the block.

I’m seeing a GI doc this Friday, but the pulmonology test isn’t available for another couple months. The thought of struggling like this is overwhelming. Any advice would be appreciated. Thank you!
