Heartburn Causes. Heartburn is actually a symptom of GERD (gastroesophageal reflux disease), and is caused by acid refluxing back into the esophagus. Risk factors include those that increase the production of acid in the stomach, as well as structural problems that allow acid reflux into the esophagus.
Renal Colic Symptoms. Back pain is in the foreground. Back pain is intense, appears abruptly on one side and may radiate to the abdomen, the iliac fossa (above the groin) and genitals. The pain can vary, with paroxysms and periods of remission but can not find any position that relieves pain.
In children, renal vein thrombosis may occur following sepsis and dehydration. Trauma is another contributor to renal vein thrombosis. Diarrhea with severe dehydration is the most common cause in children. An injury to the abdomen or lower back may result in RVT. Malignant kidney tumors that extend into the renal vein can lead to RVT.
