Hello, just thought that I would post an update as I have been to see a chiropractor today (I decided that this would be prudent as a spinal specialist might be able to help me make up my mind one way or another).
I'm 31 weeks into my second pregnancy now, and am now feeling that my ligaments are softening in my lower back. I have recently had some dull, niggling discomfort in my coccyx.
In short, the chiropractor and I discussed my previous injury and she examined my spine. She too, thought that my coccydynia had been caused by the pushing stage of my labour on 2009; she asked whether I had pushed before being fully dilated, and I think I must have as I read somewhere on my notes in ths past that I had an anterior lip to the cervix. The chiropractor said that this would have caused a contraction of the pelvic floor before everything was 'ready'. As some of the pelvic floor ligaments are attached to the coccyx, this would have pulled the tip of my tailbone inward, making the birth canal smaller. As I pushed for at least another good hour after the first twinge of coccyx pain, then the damage/inflammation gets worse.
After spinal examination, she said that my pelvic ligaments are indeed soft, but that around my coccyx is tight and sinewy, suggesting inflammation.
That I've had problems with my back with a previous labour puts me at a very high risk of damaging my spine again. She said that, as the coccyx is attached to the pelvic floor, that I risk further damaging that area, which could mean coccyx re-injury, or bladder incontinence, or prolapse.
An ELCS would preserve the pelvic floor, but would obviously weaken the abdominal wall. However, she pointed put that a) the way the surgeon cuts and b) the way the musculature is sewn together again, allows for those muscles to knit together again. Yes, they'll be weak and will need to be strengthened eventually, but that this will be possible. My sense is that the chiropractor was informing me of damage control to the coccyx/pelvic floor, at the expense of the abdominal muscles.
If I was to go for a vaginal birth, potential damage is being kept to one area, but it's the extent of the possible damage that is a concern.
Like the physio, the chiropractor thinks I'll really need Pilates exercises to get me back to strength post-birth in terms of core strength.
I certainly feel more informed now, especially as I didn't know that the coccyx is attached to the pelvic floor. My mind's not made up yet, but I'm wondering if I'd be mental now to go through with a VB ...
Thanks again for all of your advice x
