Girls, could you please tell me if anyone has ever encountered or heard about emphysema of the lungs? My sister was diagnosed with such a condition, I read that it's not very good, there are very few posts on forums. Tears well up in my eyes, I'm afraid of losing my sister?. Proper treatment hasn't been prescribed yet, we don't know what they will do, she's waiting for an ambulance, but they're not calling. I try to stay strong with my sister, calm her down and encourage her, but it's hard on my soul ?
