[|Human|] Hi, I have been have lower right pain in both my stomach and back. Yesterday I noticed I have a bruise on my stomach. I had a CT scan done as well as blood work and nothing turned up. They just said I had a bad sprain to my back. I have also noticed my stools are very pail and I have constipation as well.
[|AI|]  HI. The stool color is significant only if it is white. The bruise on the stomach can be due to a direct injury. Do you remember? There is a possibility of a retroperitoneal hematoma-this can give bruise on the abdominal wall. Bad strain on the back usually does not cause pain in the abdomen. The probable reason can be nerve entrapment due to muscle spasm. You may need to have a re-view CT scan to see the extent of damage.
