I went to the doctor with abdominal pain, he ordered an ultrasound. The came back and said they found something in my left kidney 3mm "possibly" vascular calcification or kidney stone. I had 2 follow up CT scans. One was without contrast and focused on my abdomin. The second was without contrast and was focused on my kidneys for the stone. They said I was negative for kidney stones and found plenty of other stuff wrong in other areas, anyways. They said there was no exidence of a stone but I feel a very faint, dull pain on my left side. Is it possible the CT scan missed it? I think they made 5 passes... Any help or info would be great, thanks!
