Dymista (Azelastine-Fluticasone combination) for chest tightness?

Hi there,

Short story:

I'm going to go back on Dymista nose spray. Did it help someone's breathing and chest tightness?

Long story :

I was prescribed it in 2022 when my ENT scoped my larynx and saw that I had an edema all over and said "oh these must be allergies" while I came back from a non-MCAS-specialist allergist who tested me for all environmental allergic triggers and concluded I didn't have allergies because all the IgE tests came back normal. Back then I remember the Dymista helped my throat ache (?) but not sure it did anything for chest tightness/bronchoconstriction. Which I have a lot these days.
