I have, and it occurred to me today that the SoClean experience may be the cause. Shortly after I began using the SoClean about two months ago, I developed a pressure in one ear that progressively worsened to the point of severe sinus aches. I finally went to an ENT specialist, who can find absolutely nothing that would cause the feeling of pressure and sinus aches. He ordered a CT scan which - thankfully - showed no abnormalities, and after a 12-day series of prednisone, I still had no relief from the pressure and pain. I'm going to stop using the cleaner and see if the situation in my head clears.
