My little boy is 6 years old he has had swollen lymph nodes in his neck since end of December. He lost a kg of weight in a few weeks so had blood tests in February which were normal but with reduced iron. The lymph nodes are still raised and he has been having night sweats where he is drenched and has been complaining of a tummy ache, always saying he is tired. He had a repeat blood test again showing the same results and was again referred to the paediatrician who discharged him as was not concerned. Since then I feel that the one in his neck has enlarged and is now around 20mm and more almond shape than round. At the paediatrician appointment he found an enlarged lymph node under his left arm, which I had never felt before it is still there 3 weeks later and is the size of a pea. He also says he occasionally brings up sick into his mouth and then swallows it. I want to go back to the GP as I feel that the one in his neck has increased in size and changed shape but I am concerned that they will say I am being silly and wasting their time.
