Wobbs I had the epidural with Rebecca, and ever since I wake up with pain at the bottom of my spine and it aches really bad. It is a common problem and tbh with you I still have it and Rebecca is now 2, so it might not go anytime soon!
My mum said it was the 11 or so attempts to get the fooker in!
You can see ur Dr hun who will give you a pain killer, or refer you to physio, I havent bothered but thats just cause I cant be arsed going.
Good luck xxxx
