I have a sudden sore throat (hurts on both sides of neck) that started last night. No fever, body aches, chills, runny nose associated with it. I am waiting to get in for a root canal on Thursday and have severe tooth pain for 4 days. I started amoxicillin on Sunday in preparation for the root canal along with 800 ibuprofen every 6 hours. Could the sore throat be related to the tooth or is it not usually associated?
