Comment by Retr0id

This is adjacent to what I was going to comment, which is a camera for looking inside my own ears. My ears frequently got blocked and/or itchy, and I was almost addicted to sticking qtips in to try to relieve things. There are good reasons they say not to do that! I always felt like there was wax I wasn't quite able to reach, and in trying to do so I only made things worse, often causing inflammation.

The camera cost about £10 and came with a few plastic "scraper" tools (feel kinda gross to say it, heh). It allowed me to remove the wax, and importantly, visually confirm the results. Thinking about it now, it's been over a year since I last had to use it, so I think my ears might've reached a new "equilibrium" point (they are supposed to be self-cleaning, after all).

There is, presumably, a risk of damaging your ears any time you stick something in there, so I was just very careful to not do that.
