Carbon monoxide poisoning?
I flew an old aeroplane dual and felt to some extent nausea afterwards. At first I did not take notice as it happens that I get motion sickness although the sensation did not go away for maybe 2 hours, after which I only felt sick with just a slightly elevated temperature but an elevated pulse. After a total of about 8 hours I felt just fine again.
Can you draw any conclusions of the abovementioned? Is there any correlation between the result of any medical test and the susceptibility of manifesting the symptoms of [light] carbon monoxide poisoning?
