M.,
I am so sorry that your baby is going through this. My son Ian (5 years old) has hereditary spherocytosis. This is a hereditary blood disorder (my hubby's side of the family) and one of the symptoms is enlarged spleen. The reason why my son's spleen gets enlarged is because his red blood cells are abrnormal (elongated w/spikes) whenever he contracts a virus or infection, the red blood cells go through his spleen to filtrate the virus/infection. The spleen does not recognize his blood cells and destroys them. He also gets really jaundiced (yellow skin & eyes). We discovered that he had this when he was 3 months old and suffered from enlarged spleen and screaming. I hope your testing goes well. If it turns out that your child is suffering from a blood disorder which is causing the spleen to enlarge, I know the name of a fantastic pediatric hematologist here in Tampa. I will keep your daughter and your family in my prayers. Good luck!
A.
