Hi I had the epidural drip. I had a four day drip and it worked well while it was in and then it was out and the pain returned. While it was in I could walk with help but it made it extremly hard to urinate and I got extremely constipated. I had the pain return to its full strength but none of the injections worked past a couple of hours. I now have the SCS. If you have any more detailed questions I would be happy to answer them.
