are there any?
I've been using them for a couple years now I belief...
The past couple of weeks I've noticed my ears inside getting a little itchy. When I put on the earplgus the itchiness reappears. Should I be extremely diligently at using clean/new ones? Sometimes I forget. "Ewwww" i know i know.

Are there side effects to earplugs? Also, any natural side effects? like will my ear maybe adapt to a bigger ear hole or something? lol. I feel these plugs to stretch them up a bit.
