In women, sometimes kidney stone pain can be "referred" to the vaginal area, much like in men it can be referred to the testicle. This means that the pain is felt in a location that is distant from where it is being generated. If you know you have stones and are having this kind of pain, it might be good for you to see a urologist. Stone pain, however, should have no reproducible relation to your period, so if that is the case each month, it may be something else like endometriosis,
hope you will be soon restored to health! how about a operation? friend
