I was sick for 12 hours before my best bud made me go to the er. I was nauseous, but no vomiting and no fever. I didn't have any pain in the right lower abdomen either. So, no signs of appendicitis. When the pain did start, they were just about to give me some fluids and send me home. When they did emergency surgery, they said if they had waited another ten mins, it would have burst. Never know, that is a hard one. Heck, I had mine out in 1998, and am 27. My mom had hers out this year. If you can't feel better, get your hiney to the hospital. Better safe than sorry, ya know? Best wishes to you!
