I was flying last week when upon decent of the plane i started getting an extreme pain behind my eye - it felt like a knife was trying to twist its way out of my head. The acute pain lasted about 25 minutes and when the pain landed I was left with a dull pain that is still there. I understand that this has somthing to do with the sinuses, however I am not sick, i don't feel stuffed up, my sinuses seem to be clear - and i have never had issues with it in the past... so why would this have affected me? Also is this a dangerous affliction...i know it sounds silly, but i really thought my head was going to explode at any moment, the pain was so intense i thought i was going to pass out - this coming from a mom that handled child birth with no pain meds...Thanks for your help.
