I'm having a single, involuntary cough/wheeze around the top of my lungs.
The cough is weak like a wheeze, and is chest-related instead of throat-related.
It feels like my lungs are involved, breathing in deeply makes the top of my lungs want to cough
Does it sound like I'm fighting a respiratory-bug, or are these signs of something more serious? I smoked cigarettes for 6 years, but haven't had one in 3 years.
