I've been seeing Dr Brown since arriving in Texas over 15 years ago. In the past, he gave me a physical, and did refer me to several good doctors who helped me (a lot) with a hernia, kidney stones (left kidney), AND Hepatitis C.More recently (March. 2014) when I went to him for blood in my urine. He ordered a CT scan (with contrast). After this, I had problems urinating for about 18 hours. It turns out... Using contrast for kidney stones doesn't work. I'm NOT a doctor but, from my understanding... A calcium stone will NOT show up when this is done.I was told by his Urologist that "I had NO kidney stones", and to drink more water. This seemed to help, but as time went on, I was experiencing A LOT of discomfort in my right abdomen. It got to the point that I suffered nausea, was vomiting, and had cold sweats (almost passed out from the PAIN). I thought I was going to and would have proffered to die.Finally after over a year of suffering... I went to a walk in clinic where they took a urine sample and found blood, AND bacteria. I was treated with antibiotics for infection and released. The pain was reduced in only 5 hours. Why did I listen to these guys for so long???Seems to me that if this could be properly diagnose at a walk in clinic so quickly… Dr Brown, or his associates should have found it as well. Whatever…I now have a NEW doctor. One who listens to, and CARES about their patients.Today we'll be doing a sonogram of my right abdomen to see if there ARE any kidney stones in my right kidney (or?).I’ll NOT be going back to see Dr Brown in the future.Update to this review: Turns out that there was a 2 cm stone in my right kidney after all. This what was causing the pain. I had to go to Corsicana to get a urologist to perform Shock Wave Lithotrypsy in order to get it out.
