My 4 year old son, twin 2 and had twin to twin transfusion anf was born at 33 weeks has had enlarged lymph nodes all over his body since he was 1. His neck lools like frankenstein to explain how it looks. He often suffers headaces and regulary wakes through the night complaining of a sore back. Yesterday he had a bloodtest which has shown that the body is trying to fight an infection, his liver and kidney function seems fine but we are waiting on more results. Is it normal for those glands to always be enlarged. Open to advice.
