Is there a way to tell if I broke my tailbone without being X-rayed?The injury happen more than 10 years ago,and when I mop floors or vacuum my back seems to almost lock up,and I have to stop and stand completely straight to stop the pain.The problem is in the same area as my tailbone.The pain also occurs when I sit with back bent over in an angle.Is there anything that can be done if it was broke?
