Hi Cassie,
I also have otosclerosis in one ear with tinnitus & then pulsatile tinnitus in the other. I know what you mean about your ear feeling blocked, think that's the otosclerosis. Mine was hereditary, my mum has it.
You can download tinnitus apps on your phone and customise them to make sounds that block it out - white noise, birdsong, water flowing, etc.
I tried this, along with a speaker pillow (bought on Amazon) to listen to at night, as that's when it's worse. My husband couldn't hear the sounds laying next to me. Try Tinnitus Calmer app but there are plenty available.
Hope that helps.
