My 8 year old grandson has had swollen lymph node in is neck for about a year. They just removed his VERY enlarged tonsils two days ago. The doctor said the tonsils were so enlarged that he had to bring them out to show my daughter. A month before the tonsil removal, the lymph nodes going down the side behind his ear swelled up--and one under his arm. He did not get any antibiotics after the tonsil removal. Will the lymph nodes go dow---and how long might it take to see a difference?
