FWIW, I’ve undergone both getting a tattoo in a relatively painful place (my ribcage) and natural/unmedicated childbirth, and your assessment of the pain doesn’t really line up with my experience. My tattoo is pretty small, and I suspect the wrist would be more painful, so maybe that explains the delta. But my unmedicated childbirth was also significantly faster than average, (like a total of about 70 minutes), so that should also close some of the delta.
The pain of the most painful parts of childbirth was excruciating in a way that just wasn’t in the same ballpark as the tattoo. The tattoo was more like the early parts of childbirth—hard to talk, had to focus to control my breathing, took extra mental energy to answer a question, sweating from discomfort. Transition labor was a whole other beast, though—it was like my body couldn’t contain that amount of pain and was being split open, but that the environment that it was being split open into contained pain instead of air.
Maybe the key difference is “I went through these experiences voluntarily and with the knowledge that I have the freedom to stop whenever I want.” I did not intend on having an unmedicated birth (I was open to it, but wanted the choice to be mine). Labor progressed so quickly that the medical team was unable to get analgesics to me in time. I felt completely out of control and none of the nurses in the labor and delivery room was taking control—I think no one had realized how quickly my labor was progressing. Once the midwife arrived, she took control and within ~30 seconds of her arriving, I no longer felt in terrible pain. In fact, I don’t recall feeling any pain after that. Though my guess is that transition labor was over by that point, so it’s hard to say why my pain was so greatly diminished.
It’s kind of horrifying to me that there are multiple things rated above this on the pain scale.
Anyway, it seems like there are probably a ton of people in the world who have tattoos and who have undergone unmedicated childbirth, and I’d be interested to see how their experiences compare. I’d be happy to ask some women I know if you think it’d be informative.
I’d like to read this book!
