Air plane travel with TN and Vertigo

I have a question regarding flying and TN. I have had MVD surgery that so for as been successful although I have TN now in the lower branch (jaw) and now it is beginning on the left side of my face as well. I have had problems since my MVD with Vertigo. This happened about a year ago and it hasn't came back. Once for no reason and the other while I was getting a massage the person touched the back of my neck on the side I had surgery on and it triggered it. I was afraid of flying because of this and was just curious if anyone as ever had this problem.
