I have successfully avoided double spinal fusion surgery with the lumbar steroid injections. It's like magic to my body. I've had them for 10 years, combining with Twice weekly Yoga classes, core strengthing, and modified weights (with a trainer). I see the head of a well known Pain Management Clinic. If you trust the doctor- you will be fine. It hurts for 30 seconds as I feel the medication enter my body and go down my leg. I strongly suggest trying it- Best of luck!( I am 76)
