I have a kidney stone. i feel pain in my bottom but i dont need to defectate. is this normal?

Pain in"bottom": This is not normal. It is unlikely due to the kidney stone. If you are otherwise healthy it maybe due to a problem such as an anal Fissure with her fairly extensive differential diagnosis, see a doctor if persistent

Get checked,,: This pain might be the kidney stone or it might be due to another issue altogether like hemorrhoids. Kidney stone pain is usually in the back to one side and is sharp and intense, but can vary in presentation. Considering your age, unless you've got other issues like diverticulitis, which is unlikely, this'd likely be due to hemorrhoids but see your doctor to be sure and rule out other things.

See a gyn-doc ...: To better define what you may suffer from, it would be more logical to have a gyn-doc check you out if you may have possible female pelvic related disorders first. Finding a kidney stone has been often incidental while being evaluated CT for pain somewhere in the abdomen/pelvis. A quiet non-moving stone would not usually cause pain. If moving down the ureter, intermittent unbearable pain incurs.
