Tinnitus? Ringing in the ears? Doubtful...unless you got your ear tattooed, maybe.

Bumps happen when you get hurt. The bump is just swelling.

Yes, chemicals can cause permanent ear ringing (tinnitus). The chemicals which are best studied include aminoglycosides (a type of antibiotic, such as gentamycin). Not only do these chemicals cause tinnitus, but also deafness. There are many other medications which can cause tinnitus, which is often dose related. In addition there are countless chemicals which can cause tinnitus upon exposure. Most of these chemicals come with an MSDS sheet to explain the risks of exposure.
