Hi, I have been experiencing severe right sided flank pain, gradually increasing in intensity over the past week. It is excruciating if I have to sneeze and a little less on a deep breath. I am able to pass urine comfortably, have no blood, cloudy or smelly urine. I can keep it reasonably under control with 400 mg Ibuprofen. It is worse at night when I lie down. Although it increases the pain if I rest on the right, it does feel more comfortable.
