Re: Left flank pain
It could be that you had a stone and it passed. I had exactly the same symptoms you described so I went to the doc. I had X-rays that showed nothing so I was put on antibiotics. Next the pain continued so I had a renal ultrasound that showed stones. Next I had a CT scan that showed 2 stones in the ureters. Before I could get the ureteroscopy to remove them, they passed without me knowing it. I had the procedure and no stones were found but the left flank pain continued. Once the stones passed there is sometimes inflammation and swelling where the stones were so there is still pain in the side. It's been a week since I passed the stones but flank pain remains. I was told to take Ibuprofen to get rid of the inflammation. By the way, I did have blood in the urine, urgency and frequency to go along with the flank pain. Maybe Ibuprofen will help you since infection isn't present and no sign of stones.
