oh yes, you DO want an epidural. Mine didn't work either, I could feel pain on my left side, but the helpful, delicious, important, wonderful anaesthetist came and took it out and gave me a brand new one .
The second one worked a treat, but oh my god, that pain I felt when the first one wore off! A bit like chewing off your own arm with jaggedy metal teeth (in styleee of "Jaws" from James Bond films)
I'd like an epidural every day, if I'm honest, and a few co-codamol and some red wine, but then I'm an endorphin junkie
And as for complications - they are ridicuously rare. The doctor has to tell you about them, but the most serious complication that is actually likely is a bad headache, and even that isn't the norm.
I didn't need ventouse or forceps, the pushing was easier than I imagined it would be, baby was out in 45 mins, most of which was spent waiting for contractions. Epidural turned the birth into a very positive experience, unlike that being endured by the woman in the next delivery room, who was shouting and wailing "you're HURTING me". I asked my midwife why the poor woman hadn't had an epidural, she apparently refused it. "Fair enough", I though, as I peeled my banana and flicked through "Heat" magazine..."fair enough"............
