Thank you so much for the update. I just stumbled upon this after desperately searching for answers as I have also been experiencing shortness of breath (SOB) with an unknown cause for the last 2+ years. I have been through extensive heart tests that are normal. My lung tests are good. I am also slightly anemic but nothing too crazy. I am dx with asthma but it’s very mild and only acts up when there’s a strong odor like smoke, for example. My SOB has no rhyme or reason; and will happen anytime, anywhere. 90% of the time I have chest tightness with a feeling of short of breath but 10% of the time it comes along with a runny nose which I call “attacks”. I already take multiple allergy medications and use an inhaler, as needed. I take a daily stomach medication; and magnesium and B vitamins. I’m literally doing everything I know to do to combat this feeling. It has significantly impacted my life.

Now I currently have an appt with a vocal chord specialist as two pulmonologists have recommended it stating that vocal chord dysfunction can cause SOB. I have resisted going for a year or more out of thinking it’s sheer ridiculousness but I am at my wits end with this. I even exercise to alleviate the SOB and will do fine exercising (no breathlessness) but then the feeling will be there directly after I stop. I was also debating on seeing a naturopath as I have literally run out of options. I’m starting to wonder if I have an unknown food allergy. I was tested a few years ago for food allergies and I had quite a few sensitivities but nothing I needed medication for (I take current ones for environmental). I literally do not know what else to do. I am going to try the exercise you mentioned and the naturopath. That’s all I have for now.
