Ringing in Ears
I have that and its called Tinitus. It can drive you nuts at first but you get used to it eventually. It also makes it hard to hear what other people are saying as it creates it own background noise for you.
I find that sleeping with a fan on at night, not blowing at you, helps drown out the sound.
Also during the day, keep something going like a radio or the tv. It helps drown your own noise out then.
I had tests done and they told me it was nerve damage in my ears.
The nerves are very tiny in there and easy to damage.
Mine was from a anti malaria drug called Plaquenil. It is Hydrochloroquine.
Its a powerful drug and it gave me Chemical Toxicity and that caused the damage.
They told me it was irreversible.
I had very loud buzzing at first but it got less after about 2 weeks to where it just sounds like the old tv’s if you turned the sound down. Kinda of a low whistle sound.
Try not to think about it but do what you can to drown it out.
I hope yours gets less after awhile.
