Seeking Input on Kidney Pain and IC Symptoms

I have an appointment with my gyno/urologist next week, so I will discuss this then, but I want to get input from others if possible until then. Might be long post, sorry. Also AFAB for biological context. Has anyone had IC caused irritation or whatever to the kidney(s)? It isn't constant, no fever or anything accompanying, just random sporadic feeling that's like mild stabbing plus cold feeling in that area on one side. Similar to how my bladder feels. I've been having that feeling in the lower right pelvis (around where the ovary would be) for maybe a couple months or so now, it went away after a week or two last time and they couldn't find anything wrong. The pain is less this time but is in more places (left and right side, sometimes closer to center pelvis) and now up in my right side on occasion. I don't know how concerned to be? I don't have great insurance and no money for urgent care, and don't want to go to the hospital again after how I was treated there last year.
