No, I haven't.
Trust your instincts and be your own best health advocate. If you think there's something else going on, see another doctor.
I had to do this almost 2 years ago when I found a small swollen lymph node on my collarbone after nursing my daughter one night. I looked-up the lymphatic system, found out what kind of lymph nodes they were, called my OB/GYN the next day (I was 7 weeks postpartum). He was "less than excited" about it and wanted me to come back in a week to see if it had changed. The following day, I went to my Family Practitioner because my instincts told me something else was going on. He wasn't alarmed, ordered an ultrasound and bloodwork (both of which were completely normal) and a biopsy that took 3 pathologists to determine what was going on. In my case, it was serious. I'm glad I trusted my instincts and listened to the little voice inside me.
I don't know what it might be in your case - perhaps a kidney infection or kidney stones. But, if your instincts tell you not to wait a week, don't be afraid to call another doctor or to go to the ER, Urgent Care center, etc.
Good luck.
