^^^ Well, that sounds like overall good news! But it also sounds like you may need to reflect on a new year’s resolution: get another job! I greatly admire the folks who work in hospitals on a daily basis, but the exposure to chemicals, bugs, and STRESS looms large. Maybe your skills could be applied to a related industry at a kinder, gentler location than hospital. It does seem coincidental that the hearing sensation came on in a particular ROOM at the hospital - makes you wonder about the ventilation or other unknown factors going on.
If your neck & shoulder issues relate to your job - that’s a bigger issue! In any case, have you considered physical therapy and/or acupuncture on a regular basis? I’m getting acupuncture for a curious case of “frozen shoulder”, and after 8 treatments, I CAN LIVE WITH THIS! It has really made a night & day difference. On top of which, the first question out of the doc’s mouth was: “How do you spend your day?” That led to the realization of a major trigger factor for my shoulder. Perhaps you have some triggers, too, that need to be addressed and eliminated. Wishing you continued healing and progress in this quest!
