Hello, my 6 year old granddaughter has had a history of yellow mucus with bright red blood from her rectum off and on.... often with no stool, just gas and mucus with blood.... she has a lot of GI upset and was scoped upper and lower about 8 weeks ago, all normal except her esophagus was irritated and she was placed on prevacid ER.. i think prevacid.... this eve she complained of her heart hurting and her left arm Feeling funny - she also had two episodes of the bloody mucus.... the GI doc seems not concerned. Help!
