that happens to me once in a while, sometimes it lasts a while, but when it does i say 'no weapon fashioned against me will prosper, and every thing against me i cast down' it works in a snap, its cool.
My ears ring constantly also. It IS annoying, isn't it, sounds like a head full of crickets! I believe you and I can be called "normally abnormal.) Unless I make a point to notice (my attention if called to it) I tend to overlook it most of the time. :-(
It happens to many people...self included....It is called Tinnitus. Ear drum damage from working around loud noise for years. Loud music can also be a cause. Most treatments don't work. I have the ringing 24/7 with no let up. I just live with it.
Try Tinnitus Control. It has helped with the intermittent crackling noise that I have in my right ear. I can finally sleep through the night. The daytime episodes have also been greatly reduced. Not a cure so far, but it did what it says. Provide relief. Click bellow for more info. http://tvoffersproducts.com/health/tinnitus-control/
