A week or so ago my DS (8) complained of a swollen lump in his groin, which was extremely tender. It was about the size of a kidney bean. The next day a line of lymph nodes were swollen in his neck, towards the back. I took him to the doctor on Thursday who said she'll take bloods in a month if they're still swollen. His groin is no longer painful, but its still swollen as is his neck. He's completely healthy otherwise, can't remember when he was last ill. My husband is being tested for an autoimmune condition (they think he has systemic lupus) and that's in the back of my mind with my son. Has anyone got any experiences of this sort of thing?
