I hope it works for me too! Chronic back pain sucks! The tests determined that Radio Frequency Ablation wouldn't work, so this is my last shot according to the pain doctor.............................I get those injections as well. Can barely get around without them. They last a long time for me been near 6 months since my last one and I feel the pain returning so I'll get another soon. Best relief I've found for the back so far.
Thus far I've avoided pain meds except for anti-inflammatories and Tylenol, neither of which work for my lower back but do help with hip, upper back, and neck pain.
The saving grace is that my lower back doesn't hurt when I sit or lie down, though if I sit or lie down very long my hip joints or round butt start to complain.
