Has any mum faced any complications after taking epidural? Could you pls share your experience?

I feel an epidural is the worst experience ever. I was given one for C section for my elder son. Though I faced no complications but till now face it's after effects...pain in the lower back. I never had it till after this epidural. Hence for my second son I opted for a C section under general anesthesia. I wanted to be completely out... didn't want to stay awake for the procedure. It's actually traumatic as u can hear everything the doctors speak or even get the sensation of the instruments being used. Though it's pain free but as I have a very low threshold for hospitals and operating rooms etc.i had to choose between epidural or general...
