ds1 (8yrs) has always had fairly big tonsils and a lumpy neck but today they are huge- half a centimetre off touching? Also when he lifts his head you can see a big lump on the front left side of his neck which feels hard and olive sized. He feels well, although he has been swallowing alot and ive noticed his voice sounds differnt over last week or so. Does this need checking out? Thanks
