Thank you both! I am speaking of a walking epidural not truly knowing what to call it. I had a 4 day epidural drip that was to try and numb the pain of rsd. With this epidural I was able to walk carefully and able to use the bathroom so no catheter was needed. It was just harder to do anything due to the numbness. This is what I feel like with it on. My RSD is in my ankle and it is having to be used on at least a 4.5 and up to even get a sensation in my foot. Thank you for your input and advise.
