Spinal Cord Stimulator

I feel for ya.
The injections never worked for more than a month for me. Went thru 3 rounds and I still was on the drugs. The drugs work but you pay a price over the long term and they lose effectiveness.
For me it took almost a year to find a surgeon to try to give me some relief. It took three try's to find someone and then you have to get updated pictures. I had a L2 thru L5 Laminectomy and I had a hernia too. Didn't even show up on the MRI's. Now I get the nerves burned and it last for almost a year. Next step is a stimulator but I have been dragging my feet on that but I might have to think more serious about it in the spring.
I guess my advice is to keep looking for a surgeon to try and stabilize your spine and then more conventional treatments will have a better chance of working.
