:( I'm sorry. You know, they don't tell you when you have an epidural there is a chance you might have long lasting dammage from it. I have never had good epidurals. the first was like you- they tried about 6 times but said that my scoliosis prevented it. My whole back was black from bruising and I cried myself to sleep every night for several months.
With my second I had sciatica and lots of pain after a successful epidural.
With my third I woke up in the hospital paralyzed. This was post delivery and I still had it in since I had a c-section. I had a lot of problems afterward (back pain) also. Whenever that spot on the back is pressed I am in horrible pain and that's been a few years.
So the fourth time they did it in the higher position. A few days later (about 6 or 7) I developed a spinal migraine that lasted about 2 months. I couldn't function at all.
I don't really have any pain other then if the spot is pressed.
I'm so sorry, I don't have much relief to offer you. You should tell your OBGYN and see if she can refer you to a physical therapist. He can show you some things that might help (I haven't done it but my OBGYN said her patients have had some success with the physical therapists at OGA in Houston.)
