I do. Had it 8 years, was mild at first then got louder. Mine is several different pitch rings, both ears, 24/7. Certain things can exacerbate it (caffeine, alcohol, medication, lack of sleep, illness, loud noisy places etc) so avoiding triggers is essential.
It's very difficult I won't lie but I kind of habituated to it after a few years. I could never sleep in a silent room though. I always have noise on - I use a fan, white noise cds, or apps during the night. I keep the tv or radio on as well during the day (I use the PS4 for tv stuff, makes a nice extra white noise hum) people talking or music provides extra distraction. At night it can be more of a struggle even with the white noise, so I will put either calming music or a tv show/documentary on my iPad with earphones in (I don't watch the screen) and have learned to drift of to that. It's much more preferable than trying to pretend I'm ignoring the noise.
People really underestimate how debilitating it can be.
Sorry you are struggling op but you can find coping strategies. Don't lose heart. What do you currently do to manage it? How long have you had it, did anything specific trigger it? I know of people who had it only temporarily, for example one woman had it after a head injury from a car accident. After a year it went away. As with a pp, sometimes there is a cause that can be treated too. Have you tried anything or had any tests? Mine is from noise damage - too many years in noisy nightclubs, loud concerts, and wearing earphones with music too loud! I am really hopeful about stem cell research. (I'm very protective of my daughters ears now and when she grows up I will be instructing her to wear ear plugs and keep her music at a reasonable level.)
