<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have been having acute pain in my upper abdominal area. Recently I had scans which showed my left kidney was smaller than the right kidney and rotated. My doctor said this was quite normal and not to worry, however the pain that I get in this area is quite severe with nausea and sweating. What can you suggest!!  <response>: Hi. Thanks for your query. You have got a problem of pain in the abdomen with nausea and gets severe sometimes.MVP and ultrasonography is showing left kidney is smaller and rotated. This indicated that there is a problem. I would advise you the following:Rule out other causes like Gastritis by upper GI endoscopy. It is possible that the rotated kidney is causing intermittent blockage of the pelvis of the kidney. Consult a Urologist, it is possible that passing a double J stent might alleviate the pain and if so a definite surgery is indicated.
