I guess I’m pretty lucky - I’ve never experienced many of the things mentioned here. For me, the worst pain of all was childbirth. I ended up getting an epidural, and I don’t think I would have made it all the way through if I hadn’t. As it was, I was tachycardic at the end. Granted, this childbirth was a little unusual in that they wanted to keep the fetal monitor on me at all times. They claimed that when I got up from a lying-down position, that the baby’s heart rate fell. I still think that’s not true - my heart rate was just really high, and that was what they were measuring. Anyway, because they wouldn’t let me get up, squat, walk around, take a bath, or anything that would have provided some comfort, the pain ended up being really intense. It comes in waves, so just as I thought I could handle it, it started up again. After seven hours of that, I decided heck with it, epidural it is.
In the process, I discovered that my epidural space is apparently very small, meaning that anybody giving me an epidural is virtually guaranteed to puncture it. So after giving birth, I got an epidural headache. If I laid down, the pain subsided, but my son was in the NICU, so to see him meant that I had to get up, travel up 7 floors, and then sit with him. Sitting with him was unbearably painful, like the cradle of my skull was rocking bone against bone. I got a blood patch after a day, and that ended up fixing it, leaving me with a severe but manageable tension headache.
But all of that doesn’t compare to before birth, when I had PUPPP, a vicious and poorly understood skin disease brought on by some kind of bodily reaction to the pregnancy. That wasn’t painful at all - it was itchy. Except the word itchy doesn’t even begin to describe it - mental illness does a better job. I couldn’t stop itching even though itching didn’t relieve the itch. Itching just made the rash worse, causing it to spread and to develop these thick plaques all along my legs and over my belly, and yet itching was all I could think about. Those last four weeks of pregnancy were awful. A doctor who saw me after my son’s birth (when the rash had already subsided somewhat) told me that I had PUPPP on steroids. I am praying (and I don’t pray) that if I should get so lucky as to be pregnant again, I don’t get that godawful rash.
(All in all, it was still worth it. My son is the most wonderful being in the world, and all of those experiences were, in the end, temporary.)
