I attained puberty when I was 10 years old. I undergo unbearable abdominal pain every month since then which is accompanied by nausea/vomiting, profuse sweating, sensitivity to sound etc. I have tried many meds to suppress this pain all these years, but they stop working after a couple of times. I wonder if I have become immune to them. I have had naprosyn, cyclopam, meftalspas, dolo 650, pamaspas, rantac and even tried homeopathy and ayurvedic treatments. None of them have helped me much. I have now learned to manage during the other 4 days of periods, but it's always the first day that is hard to bear or go through. Are there any other meds to combat the first day nightmarish pains? Please help!
