Hello and Welcome to Ask A Doctor service.  I have reviewed your query and here is my advice.  His tongue and throat symptoms might be due to a viral infection known as deranging which is usually associated with fever.  Or a herpes infection(non-genital).  Where are the swollen, painful lymph nodes located?  Anywhere else besides on his neck? Fever? Weight loss? Bleeding into skin? Cough?  Because how you describe the boy and with the family history, I urge you to take him to the ER as soon as possible.  Hope I have answered your query.  Let me know if I can assist you further.
