A month ago I flew abroad and experienced severe pains behind my eyes and popping in my ears. It eased over a few days, without completely disappearing, although the flight back was fine. However, a few days later the pain behind the eyes hadn't completely gone and I felt like the floor was moving. I saw a doctor who said I had labyrinthitis and gave me pills which helped. I've now finished taking them, but I'm still feeling quite dizzy with headaches and need to pop my ears very often - and am due to fly again in a couple of days. It's an 11hr flight to LA from London! Could this cause further problems? I'm currently taking a decongestant, but what can I do to help reduce chances of more pain?
