question: My son is 2 years old, had an accidental caustic ingestion about 4 months ago and has suffered from strictures of the esophagus ever since. He has had multiple balloon dilatations of his esophagus, which afterwards there has been bloody discharge the doctors always told me not to worry about. Tonight he tried to eat chicken and spit up the chicken with blood about 3 times, then clear saliva a couple more times. Should I take him to the ER? Is there something serious the blood could be a symptom of that I should worry about or is this the same type of thing where the chicken he was trying to eat dilated a stricture?
