I often hear that kidney pain is not a symptom of Lupus Nephritis, however its something that has varied through me since I first had Lupus which leaves me a tad confused. Has anyone else with LN had kidney pain? Even in the past when ive had good results and no inflamation ive had some slight pain. There are some urinary tract infections that can cause kidney pain which is treated by antibiodicts, however could a urinary tract infection last for years if untreated? Just so confused and any knowledge on the topic would be appreciated.
