My wife traveled to Nicaragua for a medical mission in March of 2011. About 8 weeks after returning home she began to have serious stomach cramping. The cramps lasted a day or two and went away. Over the last year the cramps come and go with no pattern. Now she gets constipated. She had her blood work done in late January, and everything was in the normal range. This included the liver, pancreas, and gallbladder. Her CBC and white blood cell count were all in the normal range. She has had an upper gi endoscope and everything was ok. She just recently had a ct scan which showed a 3.5 cm lesion on the liver that was hyperdense and a single swollen lymph node posterior to the pancreas. No mass was found in the pancreas, lower lungs, or kidneys, gallbladder, or spleen. Her gastoenterologist does not seem concerned about the liver lesion, but is worried about the single Lymph node. We still have no answers. Please help.
