She is 17 years old and has had these pains since she was 15. When these attacks happen she literally falls to the floor and curls into a ball due to the pain. Her mother took her to the er and tried to see what was wrong but even with tests and x rays they couldn't find anything wrong. She hasn't had her period for over a year and has still had these pains. Three days ago, after a year without it, she got her period again and the pain came harder. She has no clue and I want to be able to give her some sort of answer as to what it is and what she can do to help.
