@kaybast Thank you so very much for your information. My pulsatile T. seems to becoming more frequent as I age. It is in my right ear only and I often try to see if it is the pulsations of my heart by holding the artery in my neck, sometimes the ponding coincides and sometimes it doesn't. Wish there was much more research on this problem as it is really nerve-wracking. It is even my wake up sound now and then. Again, thank you for you article and info, really appreciate.
