Intratympanic Lidocaine as a Potent Remedy for Tinnitus in Sudden Sensorineural Hearing Loss

→ Intratympanic Lidocaine as a Potent Remedy for Tinnitus in Sudden Sensorineural Hearing Loss: A Double-Blind, Randomized Clinical Trial

This research was published this month. What I've read here and elsewhere suggests that tinnitus switches from being ear-centered to brain-centered at some point; is it possible that injections like this might make the transition less likely?

If I had read this two and a half years ago, I would have made even more effort (and I tried quite a bit) to find someone who could administer these injections. I recently got COVID-19 for the second time and am now dealing with additional hearing loss and louder, more reactive tinnitus. I'm currently looking for someone willing to administer the shots.

I’m curious about what others think and whether anyone knows of doctors or clinics offering this treatment.
