Hello Gabe, I stumbled upon your post and find myself in a similar situation.

- Cardiac evaluation shows a normal heart ( I did have some PVC's but they 're gone).
- Pulmonary assessment indicates normal lung function
- Blood tests reveal mostly normal results, albeit consistently on the lower edge of hemoglobin, suggesting mild anemia

My shortness of breath (SOB/Air hunger) lacks a discernible pattern, except for exacerbations in dry air and sometimes stuffy humid conditions. During the day when I don't think about it it's not very noticeable but during sleep some I am often in a dreamy shallow sleep because of it. I know because when it's not there I sleep much more deeply and comfortably.

Intriguingly, my passion for running remains largely unaffected, except during high-intensity speed work (track workouts), where I notice an impact on my breathing.

While acknowledging my anxiety, which may contribute to the issue, the persistence of symptoms prompts further exploration. On occasion, I resort to using an asthma inhaler at night, despite lacking a formal asthma diagnosis and there's a subtle improvement, leading me to speculate that it might be related to airway relaxation.

I find myself at a crossroads, grappling with the uncertainty of whether this is simply a part of who we are or if there's an underlying and treatable cause. Your insights would be greatly appreciated. Please share your thoughts and experiences.
