I've been having some small but strong panic attacks over the fact that the past few days I've had problems breathing. If you've ever had a lung infection, you know that feeling when you breathe and then you start coughing and then your lungs hurt. Thats the exact feeling I've had in my chest. The first day it wasn't a big deal but I woke up today and it hurt like hell. I recently quit smoking cigarettes and I think that may be the cause of my trouble breathing. I think my lungs are trying to clear themselves out but I'm not fully sure. Every time I feel short of breath I start to panic and that does nothing but make the situation worse. I fear passing out or losing my breath. Any advice would be greatly appreciated!
