That sure explains your pain. Too bad it had to come to an ER visit but at least now you are on the right track. Hope you are feeling better.

@helena4000
I have never had chest pain. I am early stage 4 emphysema so yes I feel short of breath but that is the emphysema. I was having problems breathing long before the atelectasis appeared in the scan. Don’t panic, if you had emphysema it would of shown up in your ct scan.

The pulmonologist should be able to figure out why you are having pain and difficulties breathing. I know waiting is hard.

@helena4000 I have atelectasis in both my lower lobes. There are a number of causes and of course severity. In my case I wouldn’t even know I had it if it wasn’t for the cat scan picking it up. I don’t have any pain form it. A pneumothorax is painful, atelectasis isn’t, at least not for me. They aren’t doing anything about it but that is my situation. Seeing a pulmonologist is an excellent idea. Something is going on that needs to be identified.

Its odd I wonder why they don't offer it all the time. My was done by a respiratory therapist and it was done in a pulmonary lab, maybe that had something to do with it.

Hopefully I am not too late here. When I had it done it wasn’t bad at all. They first numbed my wrist using something like novocain. That injection did pinch but it wasn’t difficult. I never felt them draw the blood. Good luck.

FYI I had mine 2 1/2 yrs ago roughly.

Morning. There is lots of really great research going on. We should all have hope, real science is amazing and the field of regenerative medicine will get us there.

I hope my posts weren't too abrupt, I was rushing to get out the door. I also didn't mean to imply it won't ever work, just that the companies selling stem cell therapy today have not undergone robust clinical studies showing it to be effective. All the class action lawsuits against the company selling it in the US would suggest otherwise.If you look at where the real science is today, it is very hard to imagine that anyone has a full blown successful stem cell therapy for lung disease.

I also need to correct something, there are clinical studies underway. There are 39 clinical studies, 14 are active. There are 12 studies that have completed, only two have published results. When results are published, it is usually because they don't have any. One of the two is the Lung Institute, the company that the FDA is trying shut down. The other one was a study done in Brazil and was legit but it was an open, non-randomized study with only 4 patients. It doesn't much look like much came from that.

However there is a lot of valid research going on so it remains hopeful. Here are some useful links I tried to keep it current, nothing older than 2017.

Feb 2018 Researchers have identified a lung stem cell that repairs the organ's gas exchange compartment, according to a new study from the Perelman School of Medicine at the University of Pennsylvania.

@merpreb There are no clinical studies, it can’t even get that far but there is early research and they are making progress. There have been a few articles on the topic but no true clinical studies, it’s just not there yet. I have to run now but this afternoon I will dig some of those links and post them.
