I'm 38 year old male, I've been complaining to my doctor's for over 5 years about my breathing, chest pains & blue skin for them to tell me it's just anxiety & it's all on my head, after a recent stay in hospital due to a number of chest infections & other problems, I had a CT scan which showed severe bullous emphysema with multiple giant bullae in both lungs, after a lung function test it showed I have an fev1 37% & further tests show I have a bode score of 8, after switching doctors they came across a scan from 2014 which showed I had it at the time but was mild & they never followed it up or even told me I had the disease, how accurate is the life expectancy as I'm told I may not have long left, 18% I'll be here in 4 years, is this right??
