Dang sorry Suzy, we've got a friend from the vape store that's waiting on new lungs, she has it tough, vapes 0mg these days, used vaping to quit of course.
*edit you typed what type while I was typing, same deal though..it makes a "scar".
they've surgically created adhesions between your chest cavity and your lungs(I'm assuming you had the mechanical method of pleurodesis. If your lung capacity is improving I'd think that'd pull on those causing pain or there's less pleural effusion going on ..not sure I'd have to see some tests(this is where you need to have an excellent Pulmonogist and or his nurse that'll shoot from the hip with you and can think out the pathophysiology of it given your volumes/diagnostic criteria, if your lungs are better or worse...so I'd suggest you slap a patch until you can have that kind of meaningful discovery, because pain is our body's way of saying "STOP IT" to us...
Daleron had a good idea, if you can do it, (if you're on an O2 concentrator and it's "squirting" oxygen in ..you'd have to take it off to do that and if you desat rapidly that'd not be good) but the old hold in the mouth and exhale through the nose to get the nicotine and "other" that us old ciggie smokers so crave.
I"m sorry that stinks, I know but you know the old joke "Patient "Doctor doctor, it hurts when I do this" Doctor: "don't do that then", kind of holds, slap a patch and have some frank discussions with your medical folks.
take care!
