Unilateral ear pain is a classic symptom for our disease, so are chronic sore throats. Tonsillectomies never remove 100% of the tonsillar tissue, meaning disease that is attracted to those tissues (SCC
HPV+) could still be attracted to that area. Please note that while all this is factual, no one can tell you over the Internet, let alone a non doctor such as myself, anything definitive. Were I you, I would move from the group of ENT's, etc. that you are seeing, and see someone at a CCC that is familiar with oral cancers, just to be sure.
