Bullous Emphysema -- Painless?

OK - For a little background - I am a fairly slender built 40's male - in 1994 while working on a car it rolled off of the ramps it was on and crushed my chest breaking all but 3 of my ribs - some in more than 1 spot - it collapsed my R lung and did substantial injuries to my chest - 1 year later i suffered a fall at work and collapsed my L lung - I have been a smoker for 20+ yrs now - since 2003 i started to experience chest pains that would get sharper the deeper the breath I took - A Dr that I was seeing kept calling it Pleuracy attacks and would give pain meds and muscle relaxers.

In early 2009 I was having pains that were a lil bit more severe than usual and went to a local emergency room and after extensive testing I was diagnosed with Bullous Emphysema - when asked by the attending Dr's what my Dr was doing about this - they were shocked that no tests or treatments had ever been started to diagnose this before now - I have also been told when I asked if I should quit smoking - Its to late for that the damage is much to sever for that to make much of a difference .....

Any way here is my questions ---- Is it true that this type of Illness or Disease is not Painful?? I am currently on pain medicine and want to know if I am the only one that has this much pain in my chest just from being alive - with every breath i take it is as if there is broken glass shards in my chest cutting and slicing 24-7. Is there anything that can make this more bearable or is there a specific type of Doctor that i need to see to help manage the pain or get help with whats left of my life ?? They say I could go in 5 minutes or 5 years they cannot say - a sneeze could collapse both lungs and thats it =[. Is it normal for Bullous Emphysema to be this PAINFUL ??
