if youre really worried get them checked even for peace of mind ! I do lots of live stuff and I got some attenuators (not ear plugs) made up they're like the ones that classical muso's wear with changeable 15 db 30 db or 45 db(eek) filters personaly I use the 15db filters which are fine .And they dont cut off the high freq's like say a foam ear plug would infact you can (almost) mix with them on .Its really worth it if you play live lots.also I get my ears checked every year (or so) cause I get a bit of tinnitus too.
