The fact that your tail bone was involved with the birth is a problem with itself. If people understood normal physiology and the birthing process.. Women would stop giving birth on their backs. It's not anatomically correct and was a practice stsrted by OBGYNs for their own convenience during the process. If prior complications are known before birth.. That's a whole nother topic, but the idea that birth is a disease process that needs treatments is a huge problem.
