Have any of you experienced any connection between your thyroid and kidney and/or bladder issues? I have had kidney stones both times my thyroid went really out of whack...once when I was first diagnosed as being hyper and once when I went hypo after RAI. My doctor says there isn't any research indicating that kidney and thyroid problems are related, but I just don't buy the coincidence. Also, has any one experienced any uncomfortable bladder pain or burning, possible from the medication? Thanks for the input.
