Hi
Good luck
I presume you are in North America as we dont have pulmonologists elsewhere. Hopefully he will say there is no problem, but in this sort of situation it is better to just pop into your local family doctor for two reasons:
1 your family doctor is used to people popping in with odd stories. They will be likely to say 'rubbish', and if the peak flow is normal confirm you are fit and well. A specialist however will run lots of tests (more money!) and be more likely to nitpick and say 'there is nothing to worry about but you may have a tiny amount of pulmonitis and I really should see you again and why dont we try a course of pulmonol.
2 If your GP confirms there is no problem and agrees the previous test was not done 'medically' it can be argued you do not need to disclose it. If you see a 'specialist' you have to disclose it and then the regulator is involved
Sadly there are many threads on this site where people have been wrongly 'labelled' with a disease and it is very difficult to get rid of the label
Let us know how you get on!
