What constitutes "anti-inflammatory treatment"? We know lots of supplements and food that seems to be universally considered healthy to have anti-inflammatory effects: olive oil, boswellia, pretty much all fruit and especially vegetables (and an infinite amount of other substance(s) (classes)). Is too much or even just a bit of those bad in some cases? Or are only the "heavy hitters" NSAID and corticosteroids bad? If so, why? Are they so much stronger? A little anecdote in regards to chronic pain: A combination of high dosage Loratadine (3x10mg) and Ambroxol (2x75mg) a day helped the chronic nerve pain in my face a lot, when NSAID didn't.
