Epidural pain

Virginia
So I had my son 2/2/17 and had an epidural done. I got to 5 cm and couldn't handle the pain. This time around he must have hit something. My last epidural the doctor at the time did a great job and didn't have any pain. Ever since I had it done and removed my left sciatica hurts everyday no matter if I sit. Has anyone else had this happen? I am praying this isn't permanent.
