I got the shakes pretty bad just before delivery and for a few hours afterwards. I don't know if that was from the epidural or the shock of a c-section to the body. And for a few weeks afterwards I would sometimes get a sharp pain in my back and would get "stuck" in a position for a few minutes. That probably happened about 10 times. All in all I would say it was still really worth it

I don't recall any side effects from the epidural. It was a lifesaver and I would highly recommend it. I didn't feel the epidural at all, and it took the edge off so I could still feel the contractions to know when to push, but they didn't hurt after the epidural.
I think the shakes are common even if you don't get an epidural, I was in the delivery room when my god daughter was born and my best friend had the shakes too, but no epidural. I had an epidural and loved it. I had been in labor 12 hours before I decided to get it, and only because I was dialating very slowly and the pain was intense because I was on pitocin to try and get me to progress, I was only at 2 cm's after 12 hours and I hadn't slept in all that time and I just needed to rest. I was able to take a nap and within a couple hours was ready to push, turns out my body liked the epidural and it helped me dialate quicker than I had been doing without it. I had no side affects other than a bruise that I would feel if I leaned up against something hard. I think it was worth it and I will likely do it again for baby #2.
