I have had my tinnitus for decades. My mother has lived with tinnitus for over 80 years do to an injury to the nerves in her ear.

Let me put this into context. There are symptoms of PCS that are just annoying and there are symptoms that are life changing.

Head aches can go from annoying to life changing (too much pain to function)
cognitive dysfunctions..... life changing
sensitivity to lights.... annoying
loss of memory skills..... life changing

Tinnitus........ annoying

Even at its loudest, and my tinnitus can get very loud, it does not stop me from doing anything. I may have to focus to listen better if the frequency of my tinnitus is competing with the sounds I am trying to hear. Mine is at about 1100 -1110 Hzs. About a C#6 Db6 on piano.

I have learned to ignore the ringing, even when it is loudest. Occasionally, I will hear a sound and need to stop to tell if it is something else ringing or just my tinnitus. It is often just my tinnitus spiking. Once I realize that, I can go on with whatever I was doing.

There are thousands of people living with permanent tinnitus. Annoying, yes, Life changing, no, except for people who have not learned how to control their anxiety levels.

Learn stress reducing behaviors and thought patterns and your tinnitus will be more tolerable. Nutrition for good nerves also helps.
