I also have two children born in the natural way and I had a blockage two years ago. My first daughter was born 12 hours after my water broke, and believe me, it HURT. Then when my second daughter was born, I asked for an epidural, no way I could tolerate that pain again. She was born within 55 minutes, with no pain whatsoever!!! I could have 10 more babies like that!!!
Now, when I had the blockage, yes the pain was bad, but the worst part for me was vomitting. If I was to compare both cases based on my experience, child birth hurt much much more!!!
