Hi, my four year old is experiencing a constant stomach ache, she is also having a very loose, grainy, pale brown stool. She had watery diarrhea for five days and now it has changed to its current state. She is lactose intolerant, which is what I thought was causing this. However, I have kept her away from dairy. Recently, right before the diarrhea started, she got into a bottle of children's Tylenol chewables and ate much more than the dosage acceptable. I took her to the emergency room and they said she was fine, there was no damage and no Tylenol in her system. I am at a loss, is there any reason I should be worried. I feel so helpless, her doctor can't get her in for another week and I don't know who else to turn to.
