Congratulations Your story brought back vivid memories of my labour with DS and the pain of a posterior labour, as well as the water injections. I agree totally, they are excruciating whilst going in but worth it for the pain relief. I was told they would be equivalent to a bee sting!! (I don't think so) Mine lasted about an hour the first time, and about a half hour the second time. I was told to wait until they pain I was feeling was at the worst it could be - but how do you know that when it is your first labour!!!!
