I can't really blame them. The essence of it is "if you see hooves think horses not zebras".
The human body is usualy one resilient bastard, so the ol' "tylenol and come back if it gets worse" is a good tactic for 95% of the cases.
But detecting those 5% cases probably takes A LOT of dedicated bandwidth from the whole medical process, so unless there is some clear manifestation that it's not horses but something else, I think it is reasonable that some will not investigate further.
