You need to run some medical tests to determine if there is a chronic closed lung disease based on the symptoms. First, you need to perform a normal X-ray to check for lung abnormality. You also need to perform a complete blood count and a few blood tests. You need to have an EKG test to make sure your heart works. You also need to make sure your organs work through glucose levels and kidney function.
Doctor, I've had a good breath for a while, and I've been coughing, and I've got a lot of spades, and I'm worried if you've got a chronic closed lung disease.
