i quit smoking almost 2 years ago. i been to emergency rooms numerous of times and had x-rays. they tell me the weird feelings: lung swelling, throat closing in, and can't breathe is my lungs reacting to smoke no longer entering my lungs and possibly anxiety. ive had a child since then, she is a month old. now i feel like this again. i'm prayerful but still a little scared. i breathe in fine someimes and somtimes i breathe in and have a scared feeling when i breathe out. if i'm doing chores i don't notice anything. i have no problems going to sleep. when i get upin the morning i'm fine. about 30 minutes later, i feel it again(throat closing). if i'm doing something i enjoy i don;t feel it. if my baby make a cry, i feel it and have a scared feeling at the same time. i am praying to God that it's all in my head. by the way, i'm 30 years old.like now when you tired, you take deep breathes. i have no problems there. if there was a problem, is there things that can be done do feel better. single mom of 2
