What causes the increase perception of Tinnitus ?

Hi everyone ! 31M here, suffering with high pitch tinnitus for 11 years or so.

I think it might be due to a auditive trauma but I cant remember for sure. Since then, I've learn to deal with tinnitus and started to live a "normal" life again : I started a band as a drummer (using customised ear protection) going to festival again, concerts, bars ect... the only moment i felt my Tinnitus was increasing was when I got a bad cold disease (having congestion in my sinnus, causing the perception of T to increase), stressfull situation, lack of sleep... you know the drill.

Recently, havng a lot of stress in my life, my Tinnitus have spiked significantly and dosent seem to go down. I've check with a doctor that said that my ears were perfectly fine, don't recall having a trauma or so. I've always been precautious during live show ect.

So I was wondering if you guys know any other reason that might cause sudden increase / perception increase of tinnitus ? PS : Sorry for the english mistakes, it's not my mother tongue !
