Consistent clicking in my left ear when i lay down. i've tried various positions, nothing helps. having a hard time getting any sleep. ?

Little Drummer Boy: What you describe could be like a "tick"(e.g. an eyelid or lip twitching,usually from "nerves,"-tension, stress, sleep deprivation,med side effect,etc).Believe it or not, there's a little muscle in there that adjusts the tension of your ear drum according to the loudness of sounds around you.It can develop a twitch too.What to do? First, get an exam to make sure nothing else is wrong in there.
