But mine only occurs during the descent of an airplane. When the descent first starts, about 30 minutes before landing. A sharp jabbing pain just above my left eyebrow. It is so painful I sometimes scream out when it first hits, and then it is throbbing and I'm sobbing, nothing makes it better except getting off the plane, and even then I feel worn out and terrible for several hours afterwards. I assumed it was something to do with dry nasal passages, but it could be sinuses.
This doesn't happenen every time I fly, either. One trip halfway around the world, out of four consecutive plane flights in 36 hours, this happened in two of the flights.
And most recently, during three consecutive flights, nothing happened. I really wish someone would explain it. But I did a Liver Flush about 3 weeks before thosest flights.
