I'm trying to figure out if I might have asthma. In the mornings, my peak flow is around 450, but it jumps to 600 after I take two puffs of duolin. The chest X-ray and CT scan look normal, but the PFT results show early small airway obstruction with a PEF of 2575 or PEFR pred at 70. They also indicated mild obstruction with an FEV1FVC of 95 and FVC pred at 80. What does all this mean? I'm really not sure and could use some guidance.

So, all my lung and chest reports came back normal, but I'm still experiencing shortness of breath. Could there be any reason for this? I had asymptomatic COVID, but it's been a while since I recovered. Why might this be happening?

I'm really worried about my husband. He's had this dry cough since last September, and it usually happens right after he finishes eating. It's like he keeps needing to clear his throat. Plus, whenever he's in cold weather, it gets worse. We've seen so many general physicians, but no one can seem to figure out what's going on. We did a chest X-ray and an HRCT in October of 2021, and everything came back clear. We also just checked his IGE levels, and they were at 1071. One doctor suggested he take montair fx for a month. Could you help me understand what might be causing this?

I'm an ex-smoker and used to smoke about 10 cigarettes a day for 7 years. It's been 6 months since I quit, but now I'm dealing with acid reflux and have pain in my chest and ribs, plus a cold. My ECG came back normal, but I'm really worried. Do you think this could be lung cancer? Also, how would I go about getting a lung cancer screening in Bangalore?
