Hello, My name is Martha Lopez I have a two year old that has been very ill for the past four days now, it began with a high fever and escalated with immense vomiting and diarrhea. Thursday my husband took him to his primary care physician and prescribed Zofran to prevent the vomiting. But through out all this disturbance of our son being ill, we forgot to mention that he was having terrible abdominal pain all thru the night, which kept him from sleeping. We went to visit the physician Friday and told us to take him to the ER we did and both blood work and urine labs were great, just a lot of potassium, but yet later that night after we got home he vomited again and the pain was so intense that he didn t sleep. Please help I don t know what to do, he doesn t have an appetite for anything? And complains of tummy ache!
