Totally. It's usually nothing, but if you don't get it checked out, once you've noticed it, feels irresponsible.
I had a comment on a completely unrelated FB post tonight (about water, FFS), from Old Guy's sister asking me to stop calling him "until she said it was okay". She said he was confused. Unfortunately, what I heard (because she couldn't even bother to post it on her brother's FB page, where I have a "he needs goods vibes please", or via Messenger) was "my son is tired of emptying his voice-mail". That might not be fair, but that's the only vibe I get from her. Painful; hate it.
