I earnestly sympathise with your plight. When my Ear was impacted, during the night my sleep was often disturbed by a constant whistling noise (tinnitus).
From what I recently read, your tinnitus might possibly indicate the presence of stubbornly lodged Wax.
Besides the Otex Sodium Bicarbonate drops, I also experimented with Otex Olive Oil drops.
Both are designed to soften hard Wax prior to water irrigation. One Otex product also includes a 'bulb' like device for irrigating your Ear once you have sufficiently allocated enough time for the drops to do their work.
If that doesn't work, a hospital visit to have the Wax suctioned out of your Ear is worth considering.
