Hi, last night, I was sitting at my computer desk and became instantly nautious. Ten minutes later, I got up and went into the kitchen, and felt extreme pain in my right lower abdominal area, it radiated to the center of my belly button, then I could feel it roll to the far lower side of my back, as if the pain in the lower right was going through. The pain is getting persistently worse, and I could not sleep well through the night. The pain is worse today. Non stop. It feels like I have to have a Bm, but I can t go. I normally have 1-2 BM s a day. I m getting nervousness about this pain. It feels sharp and pulling. I am a 58 year old female. Never have experienced this before. Any suggestions?
