I also asked this in the mens health section. I know, appendicitis right? That's the first thing everyone says in every forum I've read like this. But hear me out. I'm a 41 year old male. I've had on again, off again pains in my lower right abdomen for about 2 years. I'd go a week with it, a month without it. Today, suddenly, I've got it again and it's a little more painful than usual. I've been to the doctor about this before. I even got an ultrasound. They said my appendix was fine, and when I pointed out the exact spot of the pain, they said it was actually lower than my appendix. They saw nothing. All they could come up with was my ketones in my urine were high. It's hard to describe the exact area. When sitting, it's right on the crease line that goes between the groin and hip. Make sense? What could this be?
