I still see nothing about cortisol causing inflammation other than it decreasing our immune response during stress so that when the stress lessens or the problem (pathogen/etc) increases past a certain threshold the symptoms of inflammations would arise. But that isn't it causing inflammation in the least.

It is also important to note that the "fight or flight" response doesn't just dilate blood vessels haphazardly like inflammation does. It constricts some blood vessels and dilates others needed for the whole fight or flight phenomenon.

Not trying to be offensive or anything...I just like spreading scientific truths...
