It's important to know what is causing such seriously immobilizing pain.
And also to recognize that "anti-inflammatories" are not "pain-killers": Some pain is indeed caused by inflammation, and, when that inflammation is lessened, so is the pain caused by it.
If inflammatory pain, such as that caused by an acute sprain, for instance, is treated with anti-inflammatory supplements or meds, that pain will be temporarily lessened. It does not mean, however, that the underlying condition no longer exists, and this is critical to acknowledge. If one says, "Well, I'm 'mobile' now, because I took that pill," one might be setting oneself up for a more extensive problem.
I really hope you're trying to find out what has caused you immobilizing pain, policychecker.
