I've been suffering with lower back pain since early 2002 and over time it's been eventually diagnosed as piriformis syndrome. I've had physio, acupuncture, active release therapy, stretching, core strengthening, IMS, prescription drugs, chiropractic, tennis ball/trigger point massage, and it has degraded to a daily pain cycle. During ART I actually started getting spasms which are horrifically painful and emotionally draining.
You get to a point after spending thousands of dollars and hours getting ongoing physio and other treatments where you need a more effective solution.
Also, there doesn't seem to be a very good systematic process for diagnosing back pain and escalating treatments along a path. It is very haphazard and is usually because there is no one overseeing specialist that tracks the progress. At least that's my experience in Calgary. I am hopefully getting botox soon. One surgeon thought it was an cycle of inflamed joint and muscle tightness/spasm so to me the treatment should be to reduce inflammation at joint and relax the muscle so that it has time to break out of the cycle.
We're at 7 years now with this and the last 2 years have been brutal. At some point I think more aggressive/effective treatments need to be sought.
