What Is This? Hissing Has Been Really Bad

On top of a dreadful drone in right ear I also have a bit of hissing/sizzle in the left.
This morning at 3am I woke up and hissing was so bad, almost as if it reacts with the music coming from the radio.
Yesterday after vacuuming I could feel it being louder again.
It's almost as if outside noises are piercing through my left ear with no filters, my ear feels "wide open" if that makes any sense at all.
I'm scared and puzzled what is this.
I must say that hissing settled a bit after I went to sleep in a complete silence in the lounge.
Any input?

 

Yes, I've got hissing.. It's more in my ears now than in my head. Still trying to figure out whether I really have ETD. Sooooo frustrating!

 

Hi Valeri, the hissing in my right ear is at it's quietist in the morning and gradually becomes more intrusive as the day goes on, so by late afternoon to early evening it's starting to drive me mad!!! But strangely some days I wake up to complete silence and I have one whole day of normality. T goes of the radar altogether and too experience silence is wonderfull. This does make me realise just how debilitating T is, and it usually is back the next day. It has been like this for five years now. So any hope of it going for good are long gone.
