Here is a suggestion, just in case you might have PAIN

while flying.
For many year I suffered with lots of pain,and tried all suggestions, but nothing worked. It felt like someone was stabbing me with a knife.
One day I visited my doctor and we started talking about different things. I happened to mention about all the pain I had while flying. The then suggested taking Sudafed. Well from that day on, everything has been fine.
I take the Sudafed about 3 - 4 hours before I fly, and if I transfer, (even in flight)I will take the Sudafed 3 - 4 hours before that flight too. I try to write the time down (remember the time zone difference)for coming/going, so I will know exactly when to take it.
I hope this will help someone.
