Tonight around midnight I was at a biker rally and all of a sudden got a pain right below my belly button. It was sensitive to the touch. I felt nausea and panic. I got scared and came home. The pain comes and goes. Getting worse sometimes. When I stand up I really feel it. But sometimes when I press the area it hurts and other times it does not. What could this be. I have panic and fear I may die from it. I cant sleep. If it is appendicitis when will I know when to go to the doctor? I don’t want to wait and die from it but I don’t want to go to the e r for nothing. Its been about three hours till it started. How long should I wait it out?
