I found out that my son has Mono. Thanks for all the comments.
Hello again, I'm not sure anyone can tell you what the problem is; only a doctor can do that. It sounds like your son has Fatty Liver Disease along with an enlarged spleen which could be causing him abdominal pain. Has he seen a pediatric cardiologist for his chest pain? True heart related chest pain is very rare in children as the cause is a lack of bloodflow to the heart muscle which is a problem found in adults who have Coronary Artery Disease. Sometimes children who suffer from Hypertrophic Cardiomyopathy which is a disease of the heart muscle itself, can also have true chest pains. Most teens have muscle, cartiledge or ligament issues as the cause. Hope this helps.
I was wondering if anyone knows what that can be caused by?
Welcome to the site, dtw1398. I'm sorry to hear about what is going on with your son. Having said that, I don't understand what your question is. Can you tell me what your question is so maybe I can answer it for you?
