<s>[INST] I am a 60 yr old woman and I have had a chronic cough that makes me feel lightheaded like I m going to pass out every time I cough for 6 - 7 months day and night. The coughing comes on suddenly, almost a spasm. I have other health issues: type 2 diabetes (on insulin), peripheral neuropathy and have recently been diagnosed with autonomic neuropathy, chronic fatigue, hypothyroidism, hypertension and am on many medications to treat these conditions. My doc has taken chest xrays ( clear) and has listened to my lungs that to him sound clear. He doesn t seem concerned. I have a family history of heart disease and I m afraid that there is something else going on. What do I do next? [/INST] Thanks for your question on Chat Doctor. In my opinion you should consult pulmonologist and get done PFT (Pulmonary Function Test) to rule out bronchitis. Your age, co-existing diseases like hypertension, diabetes, your symptoms all favor bronchitis. So we need to rule out this first. For this PFT is must.  It will also tell you about severity of the disease. And treatment is based on severity only. So consult pulmonologist and get done PFT. Yuma require an antihistamine and inhaled bronchodilators. </s>
