<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello Dr,I am 35 years male. Healthy but i have been suffering from chronic throat infection 8 to 10 months, took several medicines but no or temporary results. Now a days i am feeling a bit better in terms in throat infection. But now a days from last 5 to 6 days i am feeling very tired, breadthless and feverish no fever but and very lousy. I get very shallow breadths. My recent CBC shows high ESR 15 and high heamoglobin 17.5. But i always had high heamoglobin since last 4-5 years around 18. Few days before i had some pain in my temporal region and had a very strange feeling there. I remain very depressed because of this chronic problem of throat infection and now this. My doc here did PFT test and said some problem is there i am not convinced, sorry to say that and has put me on some oral and nasal spray which is not helping taking from last 2 days. I sometimes feel pain in my right side of chest and get very very very thick phlem. I dont get coughs and when i try to take this thick phlem out from my throat, i cant and i just have to engulf it with no option. I got my all tests yearly health check up tests done and nothing wrong came in that some three months before. i m not losing weight. Please advice  <response>: Hi there. Your symptoms seem to point to your lungs - I worry if there is bronchiectasis permanent enlargement of airways in the lung due to chronic infection. In fact, the high hemoglobin you have had for the past 4 - 5 years could explain this fact i.e. your blood has had to compensate for the reduced oxygenation by your lung by increasing its oxygen-carrying capacity. The high ESR indicates an ongoing inflammatory or infectious process. A few questions to help pinpoint your problem:1. Are you a smoker? If so, how many pack years?2. Did you suffer a bad chest infection a few years ago?3. Any exposure to fungus working in moldy environment, stored grain or compost? I would like to rule out aspergilli. I strongly recommend you see a doctor to get a proper infectious disease panel done both blood and sputum along with a proper chest x-ray. Consider doing a high resolution CT as well of the lungs to help pinpoint your problem. Thank you
