question: Hi, I have a very sudden onset of sharp pain in my lower right abdomen. Judt a little to the right of my bellybutton and it hurts when I move or stretch my abdomen at all. Even if im sitting straight. I was feeling fine at the gym but when i went to get out of my car i felt a horrible pain after standing up straight. I am a 20 year old female, pretty healthy. I have had abdomen pains in the past that come and go, and changes in my bowel for a few months now. I alternate between constipation and diarrhea and my bowel is always different. What could this be?
