I am in a similar situation, u am waiting on insure to approve my unit. I am scared it will not work but in other hand I am at the end of my ropes. I have had 2 surgeries, lame, and fusion of L4 -S1. Both failed. Since then the neurosurgeon told me he could do no more for me that my wc will allow but when my case was over come see him he will fix me right. Last surgery was in 2021 and he dislocated my hips to do the fusion leaving me unable to walk right and his answer was he can pin my hips if I thought that may help.... this dr was a highly recommended dr... since we just mice to the area. Went to a new neurosurgeon and he told me by the looks of my mri he can't fix what the other dr messed up but he thinks this stimulator will help. I have sciatica in both legs All the time. Can't sit for longer that 10 minutes before my legs go numb.... making driving a no go ... and they only give me pregablin for pain . My other question is ,is it normal for your tail bone to feel like it is going to fall off? I can t stand it anny more
