My side hurts like in my back, and below my ribcage on the right. It hurts when I run or jump, but not so bad that I scream or anything. But I have to hold it when I even walk fast. My mom said she hopes its not appendicitis. Symptoms?

No loss of appetite, im always hungry. Ive only had pains for two days so far, including today. I have a fever, I just checked. It doesn't feel like theres any swelling. There is like a medium pain in my right behind my ribcage like in the body fat in between hip and ribcage too. Doesn't hurt to pee. No vomiting, sometimes cramps.
