There was a tight pain in my abdomen last night and it kept me from sleeping, I was very hot and sweaty. I still feel pain but not as bad.?

Need more info. Abdominal pain can be from many sources, some of them serious. "tight" pain makes me more worried as some bad problems can cause inflammation which results in guarding by the abdominal muscles. Hot and sweaty suggests that as well. Important info to give best answer is fever/chills, nausea/vomiting, any GI problems, change in stools, medications, etc.
