Sorry to hear you are still in so much pain and it must be difficult to try and remain positive. Sonj, you had a good response to your first epidural why are you thinking so negatively about the prospects and that you "may" need as many as 6 and then have sugery. People do recover from disc prolapses it just takes time. Everything should be geared towards helping you through this bad spell. Obviously if your pain does not settle over the next few weeks or with another epidural then surgery is an option.
Let us know how you are at the end of the week and I really hope you can report some improvement.
