Hello doctor Whenever I travel by flight I get ear pain,even though I chew the chewing gum it will not go. After landing also I will have ear pain for 2 to 3 days. And I have headache problem which I can t explain properly, I can say it is cluster headache Bcoz I get pain around right eye,right nasal passage,and right cheek. So what precautions I have to take while travelling in flight so that I will not get ear pain.
