hi and I am so sorry for your pain...I've never had surgery on my back , nor would I ...so I cann't really comment on your questions.
I wil however urge you to go to another forum where many have had back surgeries and under pain management, you will get more reponse in that forum.
PAIN MANAGEMENT COMMUNITY
best of luck
I also had a failed back surgery and know how painful it can be. What have you tried since your surgery? Have you had the steroid injections? There is also physical therapy, tens units, acupuncture, and exercise (if possible). What kind of pain are you experiencing? What level of the back did you have the surgery and what led to the surgery? Are you currently going to a pain management clinic? If not, I would make your doctor refer you to one as they are more experienced in dealing with these issues. Mine started from a herniated disc and I now have other issues going on. I posted my problems on here in a different post so if you read it maybe you can relate. I'm also looking for answers so if you have any advice for me I would also appreciate it!
I'm still working on a magic wand to fix my back and if I get it working I'll let you know!!!
So sorry you are dealing with so much pain and hope you can find a way to get some relief.
Best of luck.
