I have suffered from back pain for 14 years, I am presently on the patch and other stuff, but I still have a poor quality of life, my doctor wants me to well first to dry out and then start a pain pump that is surgically implanted. I must confess I don't know very much about them. I am not sure of what to expect,like does it work on everyone, in short I would like to know just about everything about this pain pump. Thank you for any help you can give me on this matter.
