    Ear infection and Mouth/Canker Sore

    amykyma posted:
    I am currently being treated with an ear infection. On day 2 of the ear infection, I noticed a very sore and swelling throat area (on the same side as my infection) and that night while I was asleep (or trying to sleep) the area turned into a large open sore, probably about the size of my index fingernail. It is now white and filled with pus, but so painful. I imagine this is being caused by the ear infection. Has this same thing happened to anyone else?

    The sore is located at the back of the mouth, right before/ahead of the tonsil.

    Canker sore (aphthous ulcers) are not caused by ear infections, but a canker sore in this location can definitely cause ear PAIN (not infection).

    Canker sores may be viral or just a break in the protective mucous membrane of the the mouth from abrasion (tooth-brushing, eating, etc.). You can treat this mouth ulcer separately, but they tend to be self-limiting (lasting a few days). Using a topical anesthetic, like the the ones for teething in babies, can help numb the area. There are prescription viscous lidocaine medications, but you would need to call your medical provider.

    Thank you so much for your response. This is definately not causing the ear pain as it came on after the infection. Just odd that they both happened around the same time. And I've never had a canker sore this large. Could this possibly be something other than a canker sore?

    I guess it is possible to be "something else", but your story does seem to fit the description of a nasty, aphthous ulcer. In order to know for sure, you would need to have a hands-on examination.
