My 13 yr old daughter is complaining her tail bone is hurting, it hurts to move, she tried taking a bath with Epsom salt and that didn t help, I had to help her out of the bath cuz she said it hurt to put pressure on her leg, she complained about it earlier in the year and the pain went away and now it s back, and she complains now that it hurts to move. She didn t fall or have an accident. I m debating on taking her to the ER??
