I am a 33 year old female with one Kidney. I just found out December 2011 that I only had one during other tests unrelated. For the past year an a half I have had right side pain in the area of my good, functioning kidney. I have had blood tests, CT scans, ultrasounds, visits to nephrologists, urologists, etc...I was put on Cipro even though no infection was found just in case...All tests report a good healthy functioning kidney...all tests were perfect except the left missing kidney...has anyone had similar expeience? Is it muscular? Nerve damage? I had an accident in 2002 in which I fractured my 2nd and 3rd lumbar vertabrae...does it take 10 years for never damage to appear? I am just very concerned and hoping someone has had a similar experience...Thank you.
