I had 4 ESI's in the L5-S1 without any sedation. It did hurt for a minute or so, but compared to the pain I was already in it was like a bee sting. They never worked for me but I think I was too far gone.  
 
I know quite a few people helped by epidural injections and never need anything more. In fact most of them don't understand why they did not work for me. 
 
Good luck I hope you get relief!
