Tinnitus and More...

Dear All,

I have had unilateral SSHL (sudden sensorineural hearing loss) about 8 months ago with a hearing loss of ~50 dB in the 1 kHz frequency range. I have made a full recovery in about 10 days and now (8 months later) I have perfect hearing (between 0 and 10 dB in both ears), However, I have constant Tinnitus in both ears - I have had baseline Tinnitus my whole life (But it was very very very faint), Now, I experience coming and going tinnitus in my right ear (effected ear) more then my left. It is constant for the most part, but I have these short bursts of high frequency weird noises - Like air is being let out very fast from a high pressure gradient.
However, this is not my biggest concern, I also have a 24/7 constant feeling of Ear pressure that does not go away - and I am lightheaded 24/7 as well. I have been to overt 10 different ENT's and have had every single exam done on me, all which came with normal results. I pretty much gave up trying to to fix this problem.
I am just curious to see if anyone has experienced this before?

Thanks you in advance for your time.
