question: Hello doctor, I am 25 years old. I am 6 feet tall and my weight is 86 kg. Basically my entire problem starts at night while lying down. Three to four years back, I had mild pain. While lying down I feel acute pain or some tingling in my left chest sometime it goes down around my body. When I am about to get sleep I feel short of breath then I had to wake up and sit for a while. And also my nostrils are too often blocked. For few days I had Levocetirizine and currently just using nasal drops. Consulted many doctors over the years.  As per the doctors I have nasal muscle swollen or increased which is blocking the way. I had undergone some tests of heart (ECG) and took chest x-ray. Everything was pretty normal. But from last 3-4 days my nights are hell. I could not sleep at all. I am a smoker (half cigarette per day) and drinks alcohol twice a week. Please tell me which doctor to consult? Is it something serious?
