I know this sounds odd but I wonder if anyone has experienced this: For several days now there is a persistant noise (about a volume of 3 or 4) that is with me almost always. This morning it was almost nil but then picked up again once I was up and around. It is a soft metallic sound that kind of mimics what a rattlesnake sounds like when it is rattling. No headaches, vision is fine and the sound can be bothersome but it is not so bad that I can't concentrate on whatever I am doing from moment to moment. Have you ever experienced anything like this? And yes, I know I need to get it checked out but I am unemployed and without insurance at the moment. Hopefully that will change soon.
