What you’ll find is that, for several months, I could find no physician or medical professional who knew how to address my problem. They followed the play-book for lower back problems, offering physical therapy, pain injections, and surgery — none of which were applicable. Apparently American medicine is not widely aware of inflammation of the sacroiliac joint(s), which turned out to be my problem. Thanks to my primary care physician (who is smarter than the average PCP) my problem was identified, then confirmed when anti-inflammatory injections into the joint(s) ended the pain three years ago. Read my report, then consider whether to ask your medical team about this possibility.
