My spinal lesions are pretty big, and they cause lots of symptoms when they are active, including the hug. For me that feeling normally comes with a sense of numbness & burning too.

It may very well be the hug (everyone describes it differently), but because you have a lung issue, I think it is worthwhile being checked out by your doc at this time. Being a smoker, I decided to (get checked out; COPD testing), but all was well. It seems it was just a sensory symptom, whereby I "percieved" I was having difficulty getting a full breath . . . but really I wasn't.

Welcome to the forum, and good luck with the diagnosis process, Ralph.
