Hmmm, well if google can't be your fwend, I can take a jab at it, do you have it in the lower section of your ear canal? is it happening at random spots?
oh yyeeeaahhh I've had that feeling before buddy, you just need to lie down, nothing really worked for me, it just went away on its own, soo, maybe try sticking something thin and soft in your ear, and leaving it there for a little while.
