Well Tho I myself havent flown since I have had my face pain ,
most T.N. people that I have chatted with who have flown said they were fine of corse they took their perscribed meds for t.n. before flying.
And like AV8 shared usualy if your ears pop and you feel the affects as you drive up mountian with pressure it would be the same likeness to flying.
You could ask dr. for med to relax but also tell him the meds you take now.
And hello fellow Florida T.Ner. I have a sister named Rose .
best of luck and dont worry just run by your doc . I think you will be fine!
Peace
