My 12 year old daughter has an increasing RDW. It is now at 18 when it was at 14 in the beginning of May. She was admitted to a hospital in May for an extremely swollen lymph area on one side of her neck. The doctors operated twice in May and drained the area and removed necrotic tissue. They have done many tests and all have come back negative. She is pale, weak, with chest pain and shortness of breath. Her neck is finally and slowly healing but her lips are often white and even were blue one day this week. All of her other blood counts have returned to normal but her RDW continues to increase. Please help.
