As far as body parts go, your ears are pretty low-maintenance. You don't even have to clean them out though you probably do anyway.And that's a bad idea. Especially if you're using cotton-tipped swabs to swipe at your inner ear. You can open up small cuts or lacerations in your ear canal by using swabs. You could perforate your eardrum, or force wax deeper into the ear where it can plug and cause hearing trouble or pain. While it's fine to clean at the outer rim of your ear canal if you have wax accumulating there, you don't want to dig inside. Remember that the wax has antibacterial properties to protect your ear from infection, and keeps your ear canal moist and comfortable. People think that the insides of their ears itch because of wax, but a lot of the time that itch comes when you remove too much wax and the canal dries out.
Using those ear-cleaning candles
Researchers have looked into the effectiveness of these candles, which purportedly break up and draw out your earwax. But there is no proof that candles actually do anything other than harm your ear.
Blasting music through your headphones
Loud music played through earphones could be a major cause of hearing loss. A general rule of thumb is if people around you can hear your music, you're playing it too loud.
Jamming a finger in your ear
Apart from the risks of cutting your canal or forcing wax back into your inner ear, sticking a finger in your ear is a mistake because your nails tend to conceal lots of microscopic bacteria that could cause an infection.
Piercing your own ears (or letting a friend do it)
It‘s not a good idea to pierce your own ears by needle, this may lead to infection. You want to visit a professional piercer who has the proper (and properly sterilized) instruments, to do piercing.
Not seeing a doctor about ear pain or hearing loss
In at least one way, hearing loss is like hair loss: whatever you lose is probably gone forever. We all experience a little ringing or muffling from time to time, but if it's persistent or growing worse over time, you need to see doctor.
Sticking things in your ear
Most of people are fond of scratching or digging in their ears some tools example: Paperclips, pen caps... And all could be causing cuts or earwax impactions that lead to pain or infections.
