Good post man, again I totally agree with you on this one, NSAIDs are waaaay over-used.
People don't think about why the wound or whatever is inflamed in the first place and are way too quick to just take some NSAIDs and be done with it.
As highlighted in your post, our bodies have methods in their madness and there's usually a reason for what's happening. It wouldn't make evolutionary sense if our bodies stimulated the inflammatory process and it was of no benefit to us.
Taking NSAID's just hides the issue and makes it worse in the long run. But yeah, chronic inflammation there's not much you can do other than take drugs unfortunately.
