Something's weird with my ear?

I am a very light sleeper, and have gotten into the habit of wearing earplugs every night.
I guess last night I may have pushed one in too much but didn't feel it, because when I woke up this morning my left ear felt as if it was plugged but isn't. I can hear my voice & it's just annoying. 
I can also hear my heartbeat from my left ear from time to time & it drives me insane. This has happened to me before & it's just gone away on its own. It's never lasted this long before (1 day), do I just wait it out? 
It doesn't hurt at all. I did get water in the same ear two nights ago, but I thought it all came out. What do I do??
