Hi I m 17, and this morning I got sever pain in my lower abdomen and between my stomach and legs, so I guess the pelvic area. It last for about three hours and then slowly dulled off. It s dull now but it still kind of hurts to walk. When I first got the pain it was agonizing. I could barley move and I had to clench onto the counter in the bathroom to stop from doubling over. It made me nauseous and light headed. I also experienced heat flashes. It only hurt when I moved and was full when I was still. I had experienced so upper abdomenal pain a few months before hand and it lasted for almost two weeks with all the same symptoms expect for being naseaous and having heat flashes. My mom says its just trapped gas, but I m not sure if it is. Can gas hurt that badly? I want your opinion. Is it just gas or is it something else?
