i don't know what "thing" you are talking about. was it an instrument to clean out earwax and other debris or was it just the funnel-like tip of the otoscope (the instrument with the light). if your ears hurt during the exam. and still hurts the clinician most likely scratched or abraided the very sensitive lining of the ear canal. you may need some antibiotic drops so call this person tell him the story and have him call in a prescription for you. no sense in you paying for another visit unless he plans on doing it for free.
i went to an ent who put the thing used to look inside my ears too deeply inside them and they still hurt 3 days later. it was very painful at the time and i wish after the first ear i'd said something. this makes me very scared that the pain won't go away as i initially went to the doctor because my ears were getting more sensitive to certain frequencies and ringing but not in physical pain (which is now added). i just need to know if this is something that will go away in time.
