hi there, first of all you should not take that many advils in a day, it can seriously injure your stomach lining and your kidney
, secondly if the pain is that bad then you do need to get an x-ray KUB or pelvis done. You need to visit an internal medicine doctor to begin with , he will be able to assess the nature of your problem and guide you accordingly to a specialist. In the meanwhile you could take a brufen
composition and use a doughnut pillow to sit. It may help to relieve the pain somewhat but do get a definitive diagnosis and treatment. Take care.
