My 12 year old son has been sick for 3 weeks. We ve been to the doctor multiple times. They thought he just had a viral infection that would last 7-10 days but it s been double that. He s never had fever with this sickness. He has lost 8 pounds, had chills a week ago and they just started again today...chills and then hot. He had diarrhea for a period of time and although he has less bowel movements now, he still has mucus in his stool and sometimes just has mucus. He is tired and doesn t have an appetite. He has abdominal discomfort. He s missed 3 weeks of school because he s so tired and needs to be close to a toilet. Every time we think he s getting better he begins to feel worse again.
