question: i have chronic flank pain, had kidney stone surgery in april 2011, never had any issues til now. i had ct scan and no stones, however now going for more test, due to two spots on kidney. i have headaches/nausea/hurts when i cough or sneeze . pain meds do not help. i am so tired since the flank pain has come back. doctor thinks maybe i have renel collic due to the surgery last year. i have been dizzy at times too
