I Had A Lung Function Test Done. The Doctors Office

I had a lung function test done. The doctors office called and said I have emphysema and the doctor called in an inhaler. I've read a ct scan should be the next step or should I find a pulmonary DR.?? I am a smoker and have many issues with what i think are auto-immune diseases( psoriasis , raynaulds phenomenon(maybe), dry eyes(sjogrens maybe), hypothyroid) 'Ask a Doctor'. Please type your question here...
