Age 37, white male, 181cm, 160lbs, UK, no previous health issues, not on any medication. I have never smoked.
I've had a dry, non-productive cough since around the beginning of September. It started off as an occasional very slight, tickly cough. Now it is a loud barking cough that I get when I'm active, worse if it is cold. In warm conditions when I am sedentary I slowly feel better.
The worst I felt was around November, when I felt a kind of coldness or irritation in my right lung with every breath (I've never felt anything in the left lung). It was never pain or wheezing though. It seemed to shift to different parts of the lung over time, sometimes upper right, sometimes more central, etc.
I've been to the doctor a number of times. The first two in October and November with my regular doctor, then with a doctor my dad recommended twice in December. The first doctor told me my lungs sound clear and there is nothing to worry about. The second also said I sound fine and she wasn't worried, but she did send me for an x-ray. I haven't seen this personally but she told me it came back clear. She then gave me a weeks course of antibiotics, then a few days after that completed, another weeks course of different antibiotics. I'm not sure whether it was these pills or just time but the constant discomfort dialled down a fair amount.
On Tuesday (as the doc advised) I made an appointment with an asthma nurse. She said she couldn't give me the spirometry test because she said it's pointless with a lung infection, but I was to blow into a device called a peak flow meter. Apparently for my height I should be getting 640 but I'm only getting about 550. I've to record this for a couple of weeks to see if it varies a lot over the day which would point to asthma. But she did have me use the asthma inhaler and wait for 15 minutes to try again with the blow test, the result stayed the same at 550.
I have an Easyhaler inhaler at home, I just tried it for the first time as I woke up in the cold air and felt the lung irritated. The label says salbutamol sulphate 100 micrograms. If it is asthma, should I be feeling a lot better after using this? I can't say I noticed much difference. Or maybe it is a cumulative thing.
My current doc is very helpful and I trust her. My problem is I tend to think of the absolute worst and dwell on it. So right now I'm fixated on either COPD or Pulmonary Fibrosis, things never mentioned once by my doctors. I'd love to hear some ideas about less harmful things it could possibly be, so I don't feel so depressed and hopeless about it all.
