Pretty sure there are others having chiro adjustments...question for you. Does your bum hurt? :P My bum is so sore - I've had two adjustments so far. I guess it's the SI joint, with pain in the muscles etc around it? I had issues on the right side in the exact same spot last pregnancy, so I am worried it will become as debilitating as it was at that time (I was in serious pain for about a month, it impaired mobility significantly - luckily I got it fixed up and mostly healed with lots of massage before the birth).
The chiro says it's normal and also a sign that my body is responding to the adjustments (I do indeed have some issues in the alignment of pelvic bones which, I hope, are contributing to breech presentation), but not being familiar with chiro treatment, I am still a wee bit worried. I am happy to deal with it if it's going to help baby turn *fingers crossed*
