I am 59 year old female,the problem started when I was in 5th grade and my little brother by 3 years got me so mad that I broke the rule on the cruise ship,never run on the decks because they are always slippery,so I feel hard,not on the tail bone bot on the coconut bone,pain has been with me ever since then it comes and goes but when it comes it stays,and my mother never had me checked out.
