I am having pain in my lower right abdomen.  I have been taking antibiotics for 2 weeks, but the pain continues.  When I drink alcoholic beverages, I develop a pain in my back.  Several months ago, I had a urine sample taken for a new job, and was told that a microscopic amount of blood was found in the urine.  What could be some possible causes for these symptoms? I am 55 years old, a non smoker.  I have high blood pressure, which I take medication for.  I am 51, and I am overweight. My stomach sometimes is distended.
Hello! Welcome to Chat Doctor. This seems to be due to a stone in urinary tract. Stone causes obstruction to urine outflow. Smooth muscles in ureter contract excessively to overcome the obstruction & so is the pain. Commonest stone is Calcium-oxalate stone which has spikes on its surface. These spikes cause trauma to mucosa of the urinary tract & so is the blood in urine. Many such patients are treated in my clinic to whom I advise ultrasound abdomen & pelvis, X-ray PUB, renal function tests, urine routine, blood sugar level. This helps in accurate diagnosis & appropriate treatment. Hope this information is useful for you. Wish you healthy life. Thanks. Regards.
