Afrer a year with my sob, im saying definitely the cause of sob its diffrent for everyone
Anxiety , sinusits,thyroid,gerd,asthema and ...
But the most reasons is : anxiety or Gerd
For mine its anxiety
And im on medication and feels good better 70 80 percent
But its not gone completely and im see my doc every 2 months for change medication and up or down theyr dosages
But if gerd reason of sob
Im sure its gone or better with ppi or h2 blockers medication and good diet

A friendly suggestion
If really you feel better with anxiety's meds even less
Probably Your sob cause is anxiety even your not feel it like me
So go and search for medication and dosage that it has most effect on you
Good luck
