I have a pain in my ear. the pain extends to my chew. i am taking antibiotics. is it an infection?

Maybe, or a blockage: You say the pain extends "to your chew"; I assume you mean to your JAW. If antibiotics are for strep throat, an upper respiratory tract infection, other mouth infection, it's more likely there is swelling around eustachian tube; it leads from your ear to throat; when squished, pressure builds in ear and gives ear, neck, and jaw pain. This goes away on its own. Hot salt water gargles help. Luck!

Possibly: Referred pain to the throat is commonly found with inner or external ear infections or irritations. If these antibiotics were prescribed for you by a provider they feel that based on their exam you have an infection of some time. If you started them yourself there is no way to determine if you are even taking the correct ones for what you have and you should seek medical attention/examination.
