I do know someone who had a mobile epidural in an nhs hospital, but i dont think all hospitals offer it. you would need to ask them before, i have a friend who had a ordinary epidural and it only worked in one side, so she could feel everything in one side and she actually said she was glad about that ( at least she had some feeling) and wished after that she had not had one as it made it so difficult to push. the pain is really your body's way of telling you what to do, if you listen and go with it. i had no pain relief at all for my second baby, it was painful at the end, but a different kind of pain. i totally believe in the power of the mind in getting you through it and coping with it. it was an amazing birth and so much better than my first where i had gas&air and pethidine. the difference was i was fighting the pain first time, second time i went with it kept my mind positive, it really works! good luck
