For what this is worth …

After about two years of CIDP, I woke one morning to a loud ringing/buzzing in my ear. Since it was a Saturday, I went to the local ER. They first ruled out any kind of ear or sinus infection, but when they saw I have CIDP, they immediately pushed IV steroids. They told me that was necessary to reduce swelling and, if left unchecked, could cause me some deafness. The ringing stopped pretty quickly after I received the IV and it has not come back.
