I have pain in my right side but I know it isn't my appendix, could I have gall stones or kidney stones? Would one of them give me pain in my right side? Thank you

How do you know it isn't appendix? Have you had yours removed?

The pain could be anything from gallstones to constipation. Since we can't examine you or do the necessary lab work, it's all just a guess. If it is bothering you that much, you need to see a doctor.

When you talk about your torso, divide it into quarters around the belly button - upper R and L, lower R and L.
Then try to pinpoint it further.
Then describe the type of pain and how long you've had it.
And finally, what you have had treated before!
Even then, people online can only guess.
