B: I feel dizzy. And I'm having pain in my ear. I think I am sick.
A: Do you often travel by plane?
B: No, this is the second time.

B: Why does this happen to me when I'm on the plane? I feel bad.

B: What should I do about it?

B: I'll have a try.
A: Are you feeling better now? Do you need some pills?
