Past 3 days I've had a hissing sound instead of the high pitched ringing. I have to say these days have been much easier. It's way less intrusive and easily maskable. Whereas a week ago it was bothering most of the time. Not it bothers me when I put my head on pillow or when it turns a high pitched ringing again that's only masked by a few thing but that usually doesn't last long. Couple minutes. Still bummed I have T and it bothers me when I hear it but I feel better now. So is hissing a sign in healing?
