Hi F.,
Congrats on your pregnancy! Try not to worry b/c every delivery seems to be different, as least for me.
I pretty much the same way about the epidural w/ the 3rd delivery. I had the same thing with my legs shooting out and then with the 2nd delivery I started having back pains/labor after the epidural which made me really nausious. My back was still in spasms for a while after the delivery, enough so that the anesthesiologist came back to visit me twice- once later that evening and again the next morning.
The 3rd delivery went fine. I asked for other pain relief the first time- I think that they gave me Staydol (sp?) and waited until 6 1/2 centimeters diliation to get the epidural. They said that at that point an edipural was all that they would give me, it was too close to delivery. I almost opted for nothing- was that afraid of another epidural but it went perfectly this time and I could get a little rest and I delivered 2 hrs later. Healthy baby girl.
Please don't start worrying now- just try to enjoy your pregnancy! Best wishes for a safe, painfree delivery!
