I was talking to my girlfriend on the phone and then she just stopped talking. After about 3-5 minutes i heard a gasp of air and she was back but could barely talk and still about 45 minutes later she is finding it hard to breath. I told her id bring her to the doctors but she said she doesn't want to go and I don't want to make her. Any ideas of what could've happened? A little background: she was in a car accident a few months ago and has 3rd degree heart failure and lung cancer from the airbag and smoke in the car. The doctors put her on medicine and she was supposedly getting better but she told me tonight before she went home that her chest and back were hurting her and then all this happened. Would love some quick feedback. Thank you all.
