I started to notice my tinnitus when it would be really quiet at night. That lasted a few years. Then about 5 years ago it got significantly louder after I had gotten the flu I noticed it even during the day. Just about 6 months ago I again started noticing it much louder then ever before. Unless there is much louder noises going on - I constantly hear the swishing in both my ears. I don't think masking it with hearing aids as I have read would help my problem. I only hope and pray that some day they find something to relieve this awful constant annoyance.
