Does anyone else get high frequency hissing/buzzing/electrical current, with a sharp whine and intermittent screech like sounds? I keep getting spikes of this kind of tinnitus every four to five days and can't pinpoint a cause. I find it harder to cope with this sound and it is relentless lasting the whole day and I get more distressed about it as the day progresses. Usually a good night's sleep will enable it to be gone the next day. It's spiking like this right now and I feel so low and distracted that I can't function properly. Sorry this post is not positive, but today is definitely a bad day!
