Stop Ringing Ears

ok so i have tinnitus from ear infection and i never expose myself to loud noise without ear plugs
i have just got a new motorbike and noticed it is quite loud anyway the first day i went out and wore ear plugs my tinnitus got worse. it wore off after 2 days. then today i went out and didnt wear them suprise suprise no increase or anything. why do ear plugs do this to my ears? my moto wud be about 85 dbs of sound when revved.

my tinnitus was caused by loud noise one year back…i can not hear the sound except when i close my ears with my hands or during sleeping. can the sound increase without any reason?or will it remain same if i take proper precautions in not going to any noisy place again?
