Im a 19 year old female and recently after sex with my partner i have to run to the toilet as i feel im going to vomite or use my bowles. I have really bad sever pain. I get really hot and start sweating heaps. Im short of breath and my whole stomach cramps up. The pain is so bad that im crying and trying to vomite or stop the pain. After about half an hour the pain goes away completley. This has never happened to me in my past befor. But this is the 3rd time its happened.
