I FELL BACKWORDS OFF A STOOL DIRECTLY ON MY TAIL

I FELL BACKWORDS OFF A STOOL DIRECTLY ON MY TAIL BONE. I WENT TO A DOCTOR WHO SAID I HAD RE-ARRANGED MY TAILBONE.AND TO START TAKING STOOL SOFTENERS. THEY DO NOT HELP. I HAVE LITTLE APPETITE. MY STOMACH IS LARGE AS IF I AM PREGANT. I CAN BARELY HAVE A BOWEL MOVEMENT EVEN WHEN TAKING A LAXITIVE. COULD MY TAILBONE MOVED TO A PLACE THAT CAUSES THIS?
