You are applying internet medical knowledge to real-life...they do not match up: Please stop.
I just say to look at, in case. It it not a medical knowledge use in internet.
In the best case, he had nothing and learn more, in the worse, he had some thing and be treat. In both way I don't make a diagnostic.
Saying that it is not that without exam is more a diagnostic. I think that it is positive to see all issue and take our own decision. I think that it is climbing to look at all issue and find the way to the top.
