I donīt know man but I had a cold and a week after I flew with Ryanair. Man it was the moast painfull experience in my life. I couldnīt hear and it fellt like there was a knife in my ear or something. I am a strong person and I never cry but belive me, I wanted to cry there.
A feew weeks have past now and I want to go up for training but I still canīt pop my ear so I will have to whait.
I wouldnīt reccomend the flight if you arnīt sure. It could give you big problems. So go to a doctor even if there isnīt much time left.
