Hi 6 years ago I underwent a radical neck dissection. Since the opperation I have regular sore throats which ive been told is tonsilitis(didnt realise you had more than 2 as had mine removed at 8!). Any way the last few months I have had terrible sore throats, Viral infections and then the flu after xmas. This sore throat has lasted nearly 3 weeks. so my questions:1) Does removing all lymph nodes from the neck compromise your immmune system? ie more prone to infections. 2) should I consult my oncologist due to the length of time this sore throat has been on the go! Docs will just say its viral tonsilitis even though they know history.
