ive had severe sinus problems my whole life and long flights at high altitude seem to push pressure into my ears twice now to the point of needlelike pain in ears worse than any time ive been shot or had kindney stones. am i just screwed or is there anything i can do if i fly again? its not like they can land the plane so i just sit there like ive got my head in a vice and implode. my case in particular is a rare problem with milk allergies and milk and whey products that find their way into me from random hamburger buns etc but i have neon green and neon yellow nasal discharge followed by migraine and extreme high fever then dizziness and 2 to 3 day coma once i reach my limit when im not flying and just being trying to stay alive on the ground. its not lactose intolerance, it stays in my sinuses what little traces of milk i get so its pretty different than you guys with a severe cold but i had to ask. what would you guys do if ya gotta fly in the coming months? i fly a lot but only 2 times this has really really bothered me. once 19 years ago on way to costa rica and second time on a random one of many trips to phoenix. this has certainly happened to someone else i hope. if not and you know how to relieve sinus pressure prior to flight or have any advice whatsoever it may mean the difference in my hearing a great deal so please tell me.
