I wish mine was that easy to keep away, or that there was even a way to keep it away. I had the same problem for the first time June 2014, the crystals in my ear got loose and float around messing everything up. There's a maneuver you do to get them to go back in place. I've done it at home before with help when it happened the 2nd time when I face planted in the parking lot (hitting your head can cause it) but went to the dr this time to make sure that's what it was because I don't remember hitting my head lately

I should hopefully be back running Wednesday, but for sure for my long run Sat.
