I stopped smoking in 1994 but recently i fell off my bike and had to go for an x-ray which was followed by a ct scan. i found out that i have a bulla on my lung. i have flown 8 times this year and am due to fly next week short haul to Spain. I assume that i have had this bulla for some time , but i am now worried that this might burst whilst on the plane. What are the chances of this happening
Regards
