Breathing Issues Caused By Hypothyroidism

I started having airhunger (shortness of breath) after starting Armour when diagnosed with hypothyroidism.  I was taking Armour for 3 months before the problem started.  My doctor is saying she doesn't think the airhunger is caused by the thyroid.  Has anyone else had this problem after starting thyroid medication?  I have been to a pulmonologist and had an echocardiogram and nothing has been found to explain the air hunger.  They did find chronic asthma but my symptoms of airhunger don't point towards asthma and inhalers don't help at all.  The breathing is the worst when sitting for a long time, after eating even small meals, doesn't get worse when I work out and is best when I lay down.  I don't know where to go next, I'm starting to think I am going crazy.  The past year has just been one thing after another and they say nothing is related.  It has been hypothyroidism, PCOS, skin cancer spots, low cholesterol, vitamin D deficiency, chronic asthma and I'm only 23 years old.  I don't smoke, I eat well and stick to a healthy diet and work out at least 5 times a week.  Any advice or possible answers would be great!
